Dunno, but where I come from, if the old man (the patriarch) says 'all of us', that means the whole family... I expect that's much the same in the South.

Yes

Y'all = You

All y'all = You and your family.

Also, "How's your Mama'n'em?" Meaning Mama and the whole family.

Yep... about the same up here - y'all can be 'you' or 'you and yours'... 'All y'all' can mean 'you and yours' or 'you and yours and all them other folks too,' depending on context. Don't have 'Mamma'n'em', but I would understand it fine.
