I have a pretty famous cousin. I have never met him. My grandmother had 14 kids and he is just one of the many cousins scattered across the US that I haven't met. Also, I am pretty sure he dodges all but immediate family for financial reasons.
When we were kids, my brothers, sisters and I (large family) would tell our friends and they never believed us. He was more famous then. It was very frustrating so we stopped talking about it. Now when we do share that information with anyone, they stare at us for a moment and say 'Is that the guy that was in........." Yeah it was.
My brother went to school with a kid who was a direct descendant of Jesse James. That is the height of coolness. My current boss has a niece that was on Law and Order for an entire season. We are outdone at every turn.
My mother did see my cousin last year at a memorial service for another family member. Large families are usually brought together by death. Morbid, but true. He was very nice to her. Her and my dad used to babysit him when they were dating.
I asked her what she thought. She said he was shorter that she expected......and my husband was much cuter than him.
