The families of my father and mother each have nine siblings. Most of their siblings married and had children. Some of those sibling usually the oldest ones had six children. I grew up knowing at least 40 cousins. I'm not married or in a relations ship and I don't have any children. My sister is married but no children. I see much of my generation (GenX) are in a similar state.
