A different Trastamara Queen

Out of curiosity, OTL Juan of Aragon, Prince de los Asturias' child by Margarethe of Austria was a stillborn daughter; if the POD were to be that the daughter survives instead of Juan, might she marry a Trastamara from Naples? Enrique II of Navarra? The future Karl V? Joao III of Portugal? Francois I of France?

An interesting twist would be a marriage between this daughter, call her Isabel II, and Francois (since France was a traditional ally of Castile) and seeing a much earlier War of the Spanish Succession. This would leave Anne de Bretagne's proposed marriage of her daughter Claude to Karl V possible (if unlikely). Isabella of Portugal would be the loser unless she gets fobbed off with Ferdinand I, (also unlikely since Anne of Bohemia was a better candidate) or maybe her half-uncle, Juan of Girona, Germaine de Foix's son who might or might not exist. Depends how Fernando of Aragon would take to a granddaughter.
 
By the time Germaine of Foixe rolled around the young Infanta (Isabella?) would be happily bestowed in marriage.

I think the most likely union would be with the Archduke Charles, heir of Burgundy, Flanders and Austria, though betrothals with Miguel da Paz (heir of Portugal) and Henry, Duke of York, might be considered beforehand.

With Charles never, Isabella and Ferdinand will make everything for prevented an Habsburg succession, Miguel da Paz can be a viable candidate if he will born and survive ITTL (Ferdinand and Isabella almost forced their eldest daughter to remarry for preventing the succession of Juana and her Habsburg husband and children).
Being Isabella a daughter of his eldest son is unlikely who Ferdinand will remarry with Germaine of Foix (he marry her hoping in a male heir who will have prevented the Habsburg succession in his Kingdom of Aragon)

Germaine De Foix is the Great Grand niece of Ferdinand right?

If John III of Portugal is born as IOTL he would also be most probable candidate.

Maybe not Charles, as he is the Habsburg main heir, but a second son like IOTL Ferdinand I of Habsburg would still be a candidate; probably more than a French younger prince. Still I do agree that Miguel da Paz will be the preferred candidate.

@ Kellan Sullivan: if Charles doesn't inherit the Spanish kingdoms, then he might end marrying Anna of Bohemia & Hungary.

Still the survival of the infanta could cause some butterflies; for instance IOTL Charles V, but also Anna etc. all weren't born yet.

I am a bit confused with this whole inheritance situation, but it seems like Maximillian and Mary had Philip I of Spain and Margaret. They both had a double marriage with Ferdinand and Isabella's issue Joanna and Juan. Juans dead but has issue: hypothetical Isabella II. Does she have greater claim to Spain than Philip I? It seems like Joanna is third inline, while Juan is first but with Philip I quickly producing a male heir Charles that still seems like a pretty good claim. When Isabella I died in OTL the throne went to Joanna the Mad her third daughter. While this was contested the young grand daughter of Isabella is a whole generation different than Joanna even though Isabella II is the daughter of the heir Juan.

I think the way it works if Miguel de Paz is born successfully, even if Isabella II survives as well I think Miguel wins the succession anyways. Marrying first cousins is a bad idea so I don't think Miguel would be interested in Isabella.

That being said, Ferdinand was very against an Austrian ruler, so perhaps he takes up Isabella II's banner. In the face of the Austrian influence he might see her mainly as a means to extend his Regency of Castille after the death of Isabella I. If Ferdinand is successful he might also get a major say in his Granddaughter's marriage plans.

One interesting match could be Henry the VIII. That would avoid the mismatch of Catherine with Henry. However if there is no male issue from Henry VIII the crazyness is almost too much to consider.

I don't think a French match seems very likely.

Before Juana la Loca, you have the little Infanta Isabella and her aunt, also Isabella, married to the crown prince of Portugal, any children Isabella might have in Portugal, and only then Juanna and her children.

If Ferdinand the Catholic remarries and has a son, the Infanta Isabella is still the heiress to Castille and Léon.

Miguel da Paz would be the most likely match I think, but would be interesting if Ferdinand the Catholic reconciled with his niece, Queen Catherine of Navarre, and betrothed little Isabella to Catherine's son Henry - acquiring Foixe and lands across the Pyrenees in the process.

Ok thanks for saying that. Henry of Navarre would be a good choice, since it would definitely help defend against France. With the Trastamaras being so intermarried I would hate to see Miguel de Paz and Isabella's children.

Not a bad thing: something like Philip II of Spain and his sisters, being biologically their sibling (Charles V was child of Philip I and Juana I of Castile and ATL Isabella of Spain daughter of Juan (full brother of Juana) and of Margaret (full sister of Philip); OTL Isabella of Portugal was daughter of Manuel I and his second wife Maria of Castile and Miguel de la Paz was child of Manuel I and his first wife Isabella of Castile (eldest full sister of both Juana and Maria), then the family relationship are exactly the same). Henry of Navarre is likely too much French and Miguel as Portugal's heir a much better match because they can really complete the unification of the entire Spain

If Infanta Isabella marries Henri, it means Castile will get a part of Gascony which means Castile gets a part of the areas earlier waived by Castile by the marrying Eleanor of Castile to Edward I, I think the marriage kinda nullifies the Anglo-Castillan(Spanish) alliance as well.

Hmm, so maybe if Castille takes these lands across the pyrenees and France basically buys Spanish neutrality; the English might look to tying some kind of marriage alliance with the HRE.

I think in Spain's position avoiding expensive wars and focusing on their colonies would be a good idea.
 
A match with Henri of Navarre would be interesting, especially since his OTL daughter Jeanne III was one of the foremost protestant rulers of her day. Protestant Spain anyone?

But an equally interesting match would be between Isabel II and Ferrante, Duke of Calabria - who later became Germaine de Foix's 3rd husband. Ferdinand of Aragon had no great view of Ferrante (allying with Louis XII to depose his father, Federigo IV) but he might consider it valid since it would keep Spain in the Trastamara family
 
@ JonasResende: a match with Enrique II of Navarre would render him unable to marry Marguerite d'Angouleme. Marguerite was interested, dare I say, sympathetic to the Huguenots, and raised her daughter Jeanne d'Albret accordingly. Were Isabella II and Enrique II to marry, Navarre would be detached from its pro-French position, as well as becoming heir to "their Most Catholic" tradition of Fernando and Isabella (I), therefore, it would be unlikely either to allow Protestant teachings into Spain

Secondly, the Duke of Calabria would keep Spain of a piece (in a manner of speaking), but he is descended from a bastard of the house of Trastemara, while the legal heir to Aragon et al is the Duc d'Alencon (husband of the aforementioned Marguerite d'Angouleme).

I agree, IOTL the Habsburgs ended up with the reputation, certainly the Spanish branch was a bit extreme, still even then they weren't that much different from other dynasties. However Iberian dynasties like the Trastamaras and Avis didn't have obligations against this practice, if it suited their dynastic goals; which in this case it would.
Furthermore IMHO in this regard the Trastamaras and especially the later Habsburgs were not that much different.
Still Miguel and Isabella seems a likely potential match.

There is one general issue though IOTL John of Asturias died in october 1497 and his daughter was born in december 1497. Miguel OTOH was only born quite late in August 1498, not to mention other IOTL familiar persons being only born slightly later. Even the survival of Miguel is dubious given the PoD, he might have been a she instead or a miscarriage etc.
