2. Actually, it was his father who first obtained the title, by receiving it from the Emperor.
 
Some thoughts on the next generation
A blessed Easter to all.

Saving the Aviz, Jagiellons and Valois:

François I, King of France (1494-1547) 1m: 1514 Claude de France (1499-1524); 2m: 1526 Eleonore of Austria (1498-1558)

[1m.] Louise (1515-1518)​
[1m.] Charlotte (1516-1524)​
[1m.] François II, King of France [from 1547] (b.1518) m: 1535 Isabella of Poland[1] (b.1518)​
Élisabeth (b.1539)​
perhaps offered to Edward VI?
Claude (b.1541)​
probably offered for Emanuele Filiberto of Savoy (not sure what was Henri II's reason for being against OTL Claude wedding to Savoy)
François, Dauphin de Viennois (b.1543)​
will probably marry an archduchess/princess of Lorraine?
Henri, Duc d’Anjou (1546-1554)​
Stillborn Son (1548)​
Bonne (b.1551)​
Louis, Duc de Berri (b.1552)​
[1m.] Henri, Duc d’Orléans (b.1519) m: 1533 Caterina de Medici, Duchess of Urbino (b.1519)​
Alexandre[2] (b.1537)​
maybe offered for Mary, Queen of Scots? If Scotland doesn't want a PU with France, that is. Otherwise someone like one of the d'Este girls or Henriette de la Marck is possible
Madeleine (b.1539)​
marriage to Emanuele Filiberto of Savoy or Francesco I of Tuscany is likely (Caterina might still refuse the match, but if François II says "go" what choice does she have, really?
[1m.] Madeleine (1520-1537) m: 1536 James V, King of Scots (1512-1542)​
[1m.] Charles, King of Hungary[3] [from 1541], Duc d’Angoulême (b.1522) m: 1544 Anna Maria of Ansbach[4] (b.1526)​
Charles, Prince of Transylvania (b.1548)​
perhaps an Austrian archduchess or a Polish princess (if his dad is successful in claiming the Hungarian throne). Otherwise Maria Anna of Bavaria (who OTL was proposed for Janos II Zapolya)
Hedwige (b.1550)​
perhaps part of a double Bavarian match? Or to Lorraine (if her father doesn't claim Hungary)
Anne Marie (b.1552)​
paired in Baden or Cleves
Claude (1554-1559)​
Sigismond (b.1557)​
Françoise (b.1559)​
paired in Navarre (assuming marriages there go as OTL)
Georges (b.1562)​
[1m.] Marguerite (b.1523) m: 1544 João III, King of Portugal[5] (1502-1557)​
Margarida (b.1546)​
matched with D. Carlos?
Manuel, Prince of Portugal (b.1548)​
likely to a Spanish infanta or an Austrian archduchess
Stillborn Son (1550)​
Francisca (b.1552)​
maybe a match to Savoy? Depending on who Emanuele Filiberto married
João (1553-1554)​
Claudia (b.1553)​
somebody Italian?
Affonso (b.1557)​
[2m.] Louise (b.1532[6]) m: 1545 Sigismund II, King of Poland, Grand Duke of Lithuania[7] (b.1520)​
Sigismund Franciszek (b.1548)​
either a daughter of Charles d'Angoulême (if successful in claiming Hungarian throne) or an archduchess seems likely
Karol (1550)​
Jadwiga (b.1551)​
a son of Charles d'Angoulême (if successful) or an archduke? Like Karl,of Steyr, if the emperor doesn't have a son available
Eleonora (b.1553)​
maybe somebody in Saxony, Brandenburg or Prussia?
Ludwik (b.1555)​
@Jan Olbracht could he inherit Bona Sforza's Italian lands or would those have gone to Isabella as dauphine, then passed to her second son? If so, I could see France using it as an excuse to go after Naples (again)

1. No. Casimir and Philip III revolted against John VI and deposed him in 1515. Philip at first got the old Katzenelnbogen lands while Casimir got the rest, but Philip would eventually inherit it all.
2. Yes, one branch of them are the Counts of Zollern and other are the Burgraves of Nuremberg.
3. Four - Philip IV died in May 1603 and John VIII died in September.
4. No. he didn't marry either.
5. No.
 
POD: All of Felipe II's daughters survive and Don Felipe (OTL Felipe III) dies young

Felipe II
, King of Spain, Portugal, Naples, and Sicily, Lord of the Netherlands (21 May 1527 - 13 September 1598) m. a) Maria Manuela of Portugal (15 October 1527 – 12 July 1545); b) Mary I of England (18 February 1516 – 17 November 1558); c) Elisabeth of France (2 April 1545 – 3 October 1568); d) Anna of Austria (2 November 1549 – 26 October 1580)

1a) Carlos, Prince of Asturias (8 July 1545 – 24 July 1568)

2c) Margarita I, Queen of Spain, Portugal, Naples, and Sicily, Lady of the Netherlands, twin to Leonor (6 August 1564 - 15 November 1611)[1]
3c) Leonor, twin to Margarita (6 August 1564 - 18 August 1612)[2] m. Carlo Emanuele, Duke of Savoy (12 January 1562 – 26 July 1630)
1a) Filippo Emanuele, Duke of Savoy (29 January 1584 - 2 June 1642)​
2a) Margherita Isabella (7 November 1585 - 16 January 1635)​
3a) Carlo Filiberto (14 April 1587 - 22 December 1638)​
4c) Isabel Clara Eugenia (12 August 1566 – 1 December 1633)
5c) Catalina Micaela (10 October 1567 – 6 November 1597)
6c) Juana (3 October 1568 - 2 November 1615)

7d) Fernando (4 December 1571 – 18 October 1578)
8d) Carlos Lorenzo (12 August 1573 – 30 June 1575)
9d) Diego Félix (15 August 1575 – 21 November 1582)
10d) Felipe (3 April 1578 – 27 June 1586)
11d) Maria (14 February 1580 – 3 October 1621)

[1] and [2] Please take Margarita and Leonor's names with a grain of salt. I realize it's much more likely that the pair would be named some combination of Isabel, Catalina, Juana, and Maria but I didn't want to have to think up new names for the (now) younger four girls.

I wasn't sure who Margarita would be likely to marry in this scenario. I considered Isabel's OTL husband for her - Albert, Duke of Austria but at the time of Isabel and Catalina's marriages in OTL, their younger brother Felipe was alive and kicking. I wasn't sure how much his early death would change things. Leonor I thought would be able to easily get Catalina's OTL husband - Charles Emmanuel, Duke of Savoy but tell me if that seems unlikely.

I was tempted to have Isabel marry Henri IV as I think it would be funny and I thought the year could work since it's the same year that Isabel married and Henri remarried Maria de Medicis in OTL but Isabel being nine years older than Maria, it's probably more likely that if any of the girls marry him, it's the youngest Maria who would be five years younger than Maria de Medicis at the time.

I'm totally open to suggestions on marriage options for all the unmarried girls and any of Leonor's children if her match seems plausible.

likeliest option would either be D. Sebastiao of Portugal or Duarte, duque de Guimaraes (both of whom were considered for Isabel/Catalina OTL). If neither is available (due to being dead) there might be a consideration of a Farnese or Bragança match (as OTL for Catalina) to underscore the claim to Portugal. Alternatively, Ernst of Austria - not Albrecht - was only Isabel's fiancé after Rudolf II said he wouldn't marry anyone. Likely Margarita and Ernie marry earlier here (if a Portuguese match is either unnecessary or unavailable). Which could make things interesting when Rudolf dies with no legitimate kids

POD: All of Felipe II's daughters survive and Don Felipe (OTL Felipe III) dies young

Felipe II
, King of Spain, Portugal, Naples, and Sicily, Lord of the Netherlands (21 May 1527 - 13 September 1598) m. a) Maria Manuela of Portugal (15 October 1527 – 12 July 1545); b) Mary I of England (18 February 1516 – 17 November 1558); c) Elisabeth of France (2 April 1545 – 3 October 1568); d) Anna of Austria (2 November 1549 – 26 October 1580)

1a) Carlos, Prince of Asturias (8 July 1545 – 24 July 1568)

2c) Margarita I, Queen of Spain, Portugal, Naples, and Sicily, Lady of the Netherlands, twin to Leonor (6 August 1564 - 15 November 1611)[1]
3c) Leonor, twin to Margarita (6 August 1564 - 18 August 1612)[2] m. Carlo Emanuele, Duke of Savoy (12 January 1562 – 26 July 1630)
1a) Filippo Emanuele, Duke of Savoy (29 January 1584 - 2 June 1642)​
2a) Margherita Isabella (7 November 1585 - 16 January 1635)​
3a) Carlo Filiberto (14 April 1587 - 22 December 1638)​
4c) Isabel Clara Eugenia (12 August 1566 – 1 December 1633)
5c) Catalina Micaela (10 October 1567 – 6 November 1597)
6c) Juana (3 October 1568 - 2 November 1615)

7d) Fernando (4 December 1571 – 18 October 1578)
8d) Carlos Lorenzo (12 August 1573 – 30 June 1575)
9d) Diego Félix (15 August 1575 – 21 November 1582)
10d) Felipe (3 April 1578 – 27 June 1586)
11d) Maria (14 February 1580 – 3 October 1621)

[1] and [2] Please take Margarita and Leonor's names with a grain of salt. I realize it's much more likely that the pair would be named some combination of Isabel, Catalina, Juana, and Maria but I didn't want to have to think up new names for the (now) younger four girls.

I wasn't sure who Margarita would be likely to marry in this scenario. I considered Isabel's OTL husband for her - Albert, Duke of Austria but at the time of Isabel and Catalina's marriages in OTL, their younger brother Felipe was alive and kicking. I wasn't sure how much his early death would change things. Leonor I thought would be able to easily get Catalina's OTL husband - Charles Emmanuel, Duke of Savoy but tell me if that seems unlikely.

I was tempted to have Isabel marry Henri IV as I think it would be funny and I thought the year could work since it's the same year that Isabel married and Henri remarried Maria de Medicis in OTL but Isabel being nine years older than Maria, it's probably more likely that if any of the girls marry him, it's the youngest Maria who would be five years younger than Maria de Medicis at the time.

I'm totally open to suggestions on marriage options for all the unmarried girls and any of Leonor's children if her match seems plausible.
Margarita would marry Archduke Ernest of Austria as soon Felipe died. As Catholic Kings of the right age are missing Leonor could end as Duchess of Savoy and her other three sisters married to Italian or German rulers… Or Margarita could have been already married to Ernest (with the Netherlands promised to them) with Leonor being the unlucky fiancée of Rudolf (with her eventually marrying either Matthias or Albert with the Netherlands as dowry) and Isabel as Duchess of Savoy and Catalina and Juana elsewhere in Italy or Germany

I highly doubt that Margarita would be allowed to inherit the Spanish domains and the Low Countries. I think more likely is one of the twins being Queen of Spain, Naples, Sicily, Sardinia, etc. and one of the twins being Lady of the Netherlands. Also, I personally like the idea of whichever twin inherits Spain marrying https://en.wikipedia.org/wiki/Duarte,_Duke_of_Guimarães_(1541–1576) while the one who inherits the Low Countries marries her cousin Archduke Ernst.

First, I can't see Henry VII even considering remarriage after Elizabeth's death if he has two sons still living from her. Second, Arthur and Katherine of Aragon's daughter is absolutely not going to be marrying Charles V with her Uncle Henry still alive. She will be marrying Henry VIII, or Edmund should something happen to Henry. Third, I would switch the matches of Elizabeth Tudor and Mary Tudor as I'm fairly certain that Charles Orlando and Elizabeth were betrothed even during their brief lives IOTL and Christian II would only be taken into serious consideration after his father's death, by which point Elizabeth is almost certainly already married in France. And finally, Jane Tudor and Anne Tudor would not be sovereign duchesses, but they would inherit any lower titles that their respective fathers held (ie countess of Richmond/countess of Bedford).

Arthur‘s daughter would be either married to her uncle Henry or sent in a convent as everything else would cause troubles for the Tudors. Henry VII here would have no reason for marrying again (or try to have the last child who killed Elizabeth) with two sons still alive. If she was still born Katherine of England would be the one engaged to Charles V (and Arthur’s daughter would be called either Elizabeth after both her grandmothers or Margaret). Anne Boleyn would NOT receive any title of her own and Jane Seymour would NEVER be seen as good enough for becoming a royal Duchess (Elizabeth Grey, Viscountess Lisle would be a far likelier bride). Edmund of Somerset would marry Madeleine de la Tour d’Auvergne NOT Louise Borgia and I doubt who James V would be able to get a sister of Charles V as bride. Also Elizabeth Tudor would be the one to marry the King of France with her younger sister Mary marrying to Christian II of Denmark or Charles V
