So in my playthroughs I like to give third/fourth sons (who have almost no chance of inheriting the main title) a wife from a prestigious house (or a fourth son from a lesser house and a wife from my own) and a landed title and then I save edit to make them a cadet branch, with the name and sigil a combination of the parent house and the wife's house. Having trouble coming up with names though so if anyone has any ideas for my next Targaryen playthrough please do let me know. I have some so far:
Targaryen+Stark = Whitewolf
Targaryen+Arryn = Wingflame
Targaryen+Hightower = ?
Targaryen+Velaryon = ?
Targaryen+Blackwood = Fyretree
Targaryen+Darry = ?
Targaryen+Lannister = Goldfyre
Targaryen+Reyne = ?
Targaryen+Dayne = ?
Targaryen+whoever =
If you have any other house combination feel free to add a comment
