I currently have four families in my game.

My "Cookie" family is now on generation 5. In this family, I keep all of their original names for a bit of variation.
Phantom, the gen 4 child that got the house, is now 37. His wife Saphette is 39. They have 6 children: son Zif (11), daughter Icona (9), daughter Alfa (8), son Bluff (5), adopted son Bingu (5) and son Tico (3).

The "Os Bichinhos" family is also on generation 5. In this family, only females are allowed to inherit the house.
The current "heiress", Vera, is 35. Her husband Paulozo is 34. They have 5 kids so far: daughter Elizabeth (10), son George (8), daughter Salome (5), son Littlefinger (3) and a baby son whose name I haven't decided yet.

The third family, the "Jo" one, is on generation 4.
Toby is the gen 3 child that inherited the house. He is now 29. His wife, Sophie, is 31. Their children are Stephen (7), Brian (5), Beatrice (4) and Ellen (2).

The last family ("Fred Fredburger") is only on the third generation.
Only two people are left at home now: Beyond from generation 2, who is 47, and his wife Roxy, who is 46.
Their six children (triplet girls Lisabeth, Bethann and Annalisa, twin boys Jonathan and Matthew and youngest son Tyrone) are all at college.
After Beyond and Roxy die, Lisabeth will come back to the house. I think this will be the first time ever for me that a child that is part of a set of multiples will inherit the house.
