Dear Anonymous,
My father was an only child. He had no siblings for me to have a cousin. That would leave my grandparents, but I can confirm for you that they are already dead.

As for the maternal side of my family, it could be possible that I have cousins, and as a result, aunts or uncles, but I could not guarantee you that for sure. I have no memory of my mother as a child. For the twenty six years that I’ve been alive, no one has ever reached out to me claiming to be related to my mother.
