Minor - Major characters

[toledo]

After a few shenanigans I find myself back down to 6 major characters....but for the life of me I can't see a way to promote a minor character to major?

That said, the minor characters I have that are 18+ were not born Toledo so I'm wondering whether to be a major character the character has to have been born to the household?

any thoughts on this?

If the option isnt there on the character scree, It might be a bug, I've certainly promoted a forign born charcter to major.
