My grandpa's sister is also my great grandma's sister from my grandma's side.
ex./ my grandma = Alyssa
my grandpa = Charles
my grandpa's sister = Elizabeth
my great grandma/ my grandma's mom = Hailey
Charles' sister is Elizabeth. Elizabeth married Hailey's brother. Alyssa is married to Charles.
This makes Elizabeth Alyssa's sister in law, and her aunt as well.
My question is how I'm supposed to make Elizabeth the 'same person' on my tree. Thanks.
