I'm about 99% convinced I'm not going to mention this in my query letter, but that 1% is nagging at me.

My second cousin was a super famous writer. This has no place in my query letter, correct?

After all, I never even knew him, he wrote in a different genre, it'll probably sound like name dropping, and being related to someone famous doesn't mean my writing's any good.

At the same time, I keep wondering that if the agent is a fan of my cousin, that maybe it'll prompt them to give my pages a shot. And there are a lot of people that go nuts over his stuff.

I guess I'm just looking for confirmation if I'm doing the right thing by leaving it out. Thoughts?
