Suppose Henry FitzRoy is married to Mary I (his half-sister) and becomes King of Ireland as Henry VIII had intended. Let's assume all of this happens before Anne Boleyn discovers she is pregnant (with Elizabeth in 1532). Let's also assume Henry FitzRoy survives for a good while.
What are the effects of this if...
A. Elizabeth I is born exactly as OTL and events transpire similarly?
And for fun...
B. Elizabeth is born a male (Edward VI, b. 1533), and Anne Boleyn's second child with Henry VIII is a female (Elizabeth I, b. 1536) but although the babies are healthy and grow passed childhood Anne dies in childbirth with the girl in 1536?
In either (or both) scenario(s) what are the effects of Henry FitzRoy marrying Mary I, other than being rather icky, and what are the effects of him being created King of Ireland?
Effects on Ireland? Effects on succession? Possibility or probability of children? Etc.
