I've posted the initial family structure rules before, but not the Build a Clan Workshop. Enjoy.

Random Tsolyáni Family Structure

Family Creation

Start by rolling a d6, d8, d10, and a d12.

Parents: d10-1

Siblings: d12-2

Add +2, if 4 parents or more.

Spouses: (optional)

d8	Spouses
1-4	Not married
5-6	1
7	2 (+1 on Child roll)
8	3 (+2 on Child roll)

-2 if person is 20 or less

+1 if person is 31 or more.

+1 if person is female

+1 if person lives in a rural area

Concubines: (optional)

Roll again on the Spouse Table without modifiers for the number of concubines.

Children: d6-3

-1 if person is 20 or less

+1 if person is 31 or more

Each roll is an open-ended roll. If the maximum roll is rolled, roll the same die again, apply the same modifiers, and add the result to the total. For instance, if rolling parents, if you roll a 10 (-1 = 9), roll d10-1 again and add to 9.   

Build Your Own Clan House for Fun and Profit

Using these rules you can generate an entire clanhouse.

Clan Elders

Clanhouse	Rural	Urban
Small	d4	d6+2
Medium	d6	d8+2
Large	d8	d12+2
Huge	d12	d12+4

Urban Clanhouse: add 2 to result

Then take the Clan Elders through family creation and two more generations down.

1st generation: For each elder, get siblings, spouses, and children. For each sibling, get spouses and children.

2nd generation: Then for each child, get spouses and children.

3rd generation: Then for each child, get spouses and children.

The brothers of fathers are clan-fathers. The sisters of mothers are clan-mothers. The wives of clan-fathers are clan-mothers. The husbands of clan-mothers are clan-fathers. The sisters of father are clan-aunts, and the brothers of mother are clan-uncles. The wives of clan-uncles are clan-aunts. The husbands of clan-aunts are clan-uncles. The children of clan-mothers and clan-fathers are siblings. The children of clan-aunts and clan-uncles are clan-cousins.
