List of Alternate Monarchs and Aristocratic Lineage

In celebration of Queen Mary I's 505th Birthday:


Queen Mary I "The Catholic" (1516-1565), reigned from 1548 [1] M. King Philip II of Spain (1527-1598), had issue

1. King Arthur I of England and the Netherlands [2] (1549-1591) M. Anna of Austria (1549-1595)
2. Philip, Duke of York (1551-1609) M. Maria Anna of Bavaria (1551-1599)
3. Princess Catherine of England (1553-1609) M. King Sebastian I of Portugal (1554-1592)
4. Princess Mary (1556-1610) M. Holy Roman Emperor Matthias I (1557-1619)

...

[1] Edward VI dies earlier here, so Mary is able to take the throne after a brief rebellion by her.
[2] The Netherlands are given to the English as part of Philip’s dowry to Catherine. Don Carlos is also born healthier (his mother still dies in childbirth), so he isn’t mad and is able to rule Spain.

Mary Queen of Scots is more successful in her reign thanks to her English cousins and rules for a much longer period than in otl and has more children.

Why is Philip of Burgandy the second? I can't find any other holy roman emperors named Philip.
 
An idea I've had for a while;

King Arthur I "The Good" (1486-1537), reigned from 1510 M. Margaret of Austria (1480-1535) [1], had issue

1. Princess Margaret of England (1503-1560) M. King John III of Portugal (1502-1557), had issue

1 (A). Prince Joao Manuel, later King Manuel II (1521-1579) M. Marguerite of France (1523-1560)
1 (B). Princess Margarida Maria (1523-1560) M. King Philip II of Castile and Aragon [2] (1523-1598)
1 (C). Prince Henrique of Portugal "The Wise" [4] (1525-1578) M. Eugenia of Braganza (1525-1562) [3]

2. Princess Mary of England (1505-1560) M. King Charles IX [4] (1504-1559), had issue

2 (A). Princess Marie of France (1522-1563) M. Holy Roman Emperor Maximilian II [5] (1525-1570)
2 (B). Princess Marguerite (1523-1568) M. Joao Manuel of Portugal (1521-1579)
2 (C). Princess Anne Of France (1525-1560), became a Nun
2 (D). Dauphin Louis, later King Louis XIII (1527-1578) M. Elisabeth of Austria [6] (1528-1580)

3. King Henry VIII "The Catholic" (1506-1559) M. Beatrice of Portugal (1504-1555), had issue

3 (A). King Arthur II of England (1522-1580) M. Princess Elizabeth of Scotland (1519-1578) [7]
3 (B). Edward, Duke of Somerset (1524-1560) M. Catherine Howard [8] (1523-1550)
3 (C). Edmund, Duke of Richmond (1526-1569) M. Gertrude Manners (1525-1560)

4. Cardinal Edward of England (1508-1580), never married


...

[1] The POD is Catherine of Aragon dying in 1496 of a cold. Hence when Margaret is widowed a contract is arranged to marry her to Arthur.

Maximilian, Prince Imperial of Mexico (b.1864)

------------
Maximilian II, Emperor of Mexico (b.1864: d.1919) m Infanta Maria of Spain (b.1861: d.1923)

Issue:

Carlotta, Princess of Yucatan (b.1879)

Maximillian III of Mexico (b.1880)

stillborn daughter (b.1882: d.1882)

Isabella of Mexico (b.1884)

Alfonso of Mexico (b.1887: d.1900)

Francis José of Mexico (b.1891)
 
Wouldn't these titles be swapped? I thought the older brother would get the more important title.
No, Edward John is the son of Shrewsbury by his first marriage while Francis is his son by his second marriage. Brittany is Francis' maternal inheritance.
Exactly. Edward John is the son of Anne Mowbray, while Richard’s other children are born by Anne of Brittany. If you see the age gap between Edward of York and Francis of Brittany is pretty big
 
Edward IV decides against marrying a "Mere widow of England." So Enrique III takes the opportunity to get rid of his troublesome half-sister by making her Queen of England. Another part of the POD is that Isabella's only full sibling, Alfonso, Prince of Asturias isn't poisoned and marries their "Niece" to settle the succession dispute in Castile. I also think Isabella being in England during the Wars of The Roses to be interesting, as she'd give Margaret d'Anjou a run for her money....

Edward IV of England (b.1442, d.1490) (1) m. Isabella of Castile, Queen of England in 1466 (b.1451, d.1506) had issue
1) Elizabeth of York, Holy Roman Empress (b.1466, d.1518) m. Maximillian I, Holy Roman Emperor (b.1459, d.1519) in 1483, had issue
2) Stillborn son (b.1468)
3) Edward, Prince of Wales, later Edward V of England (b.1471, d.1535) m. Anne of Brittany, Queen of England (b.1477, d.1514) had issue, including Edmund I of England (b.1495) second marriage to Susanna of Bavaria (b.1502, d.1543) had issue
4) Richard, Duke of York (b.1473, d.1492) m. Margaret of York, Suo Jure Duchess of Gloucester in 1490 (b.1475, d.1530) had issue, including Edmund, Duke of York (b.1490) and Richard, Duke of Gloucester (b.1492) (2)
5) Cecily of York, Queen of Scots (b.1475, d.1537) m. James IV of Scotland (b.1473, d.1533) had issue
6) Mary of York, Queen of Castile (b.1479, d.1539) m. Enrique V of Castile (3) (b.1482, d.1545) had issue
7) Eleanor of York, Queen of Denmark, and Norway (b.1479, d.1550) m. Christian II of Denmark and Norway(b.1481, d.1559) had issue
8) John, Duke of Somerset (b.1484, d.1557) m. Alice de la Pole, Suo Jure Countess of Lincoln (4) (b.1485, d.1549), had issue

(1) I imagine that Isabella would be much more concerned about her husband's gluttony than Elizabeth Woodville, and would try to curb it, thus he lives longer (Though if he still died in 1483 per IOTL, a clash between Isabella and her brother-in-law Richard would be interesting)
(2) Daughter of Richard Duke of Gloucester and Anne Neville, since Richard dies of illness in 1488 she inherits his lands, becoming the greatest heiress of all England and naturally marries her young cousin, until he dies of Tuberculosis.
(3) Eldest surviving son of Juana la Beltraneja I of Castile and her "half-uncle" husband Alfonso XII.
(4) Daughter and heiress of John de la Pole, 1st Earl of Lincoln, who dies in a hunting accident in 1488

I think without Richard's fear of the rising power of the Woodvilles, he would be content with remaining Lord Protector while Isabel retains custody of her children. Isabel doesn't have a seemingly endless supply of relatives with which to sway his nephews like Elizabeth Woodville had and would be somewhat isolated. And just like Margaret of Anjou, Isabel would fiercely defend the rights of her son. Furthermore, both Richard and Isabel were intensely pious, so I think they actually would have gotten along pretty well.

I suppose Warwick could still betray Edward IV since Warwick was trying to retain his control over Edward partially by arranging the alliance with France through marriage (Bona of Savoy if I recall correctly), unless Edward and Warwick agreed that Isabel is a good compromise wife. Castile didn't bring much politically to England though and had it's own financial problems, but Isabel did bring generations of royal descent through John of Gaunt (both maternally and paternally) and thus Edward III.

True, I think Isabel would be more likely to see a rival in Warwick rather than Richard. In fact, rather like her own mother did with Álvaro de Luna, she may be the one that provokes the break.

Margaret can not inherit the Dukedom of Gloucester, but if her aunt Isabella died young or childless (as you are implying here) then Margaret would be suo jure Countess of Warwick and Countess of Salisbury once her mother and maternal grandfather died
