My wife says my family tree is a Banion tree.
My Mom’s 1st husband was my dad’s, her 2nd husband, cousin.
Therefore my half sisters are also my cousins. And their children are my nieces an nephews along with being my cousins.
I also have nieces and nephews that are about my age.
My older brother’s sister in law married one of our nephews-cousins. So his Nephew is also his brother in law and his cousin.
My second oldest brother’s sister in law married another nephew-cousin.
So their children are my brother’s nieces and nephews, also their great nieces and nephews, and cousins.
