This is totally AU but if Henry had 3+ children and betrothed them while they were in childhood (I.e while he was alive), who do you think he would marry them off too? As in the best choices (strongest allies, etc) obviously considering his break from the Catholic Church!
Child 1 - Female (born 1516) Mary I
Child 2 - Female (born 1533) Elizabeth I
Child 3 - Female (born 1535)
Child 4 - Male (born 1537) Edward VI
Child 5 - Male (born 1541)
Child 6 - Male (born 1542)
Thank you all for your help!
