Ok, I see where the confusion is. My husband is Daniel O's son. Daniel married Paula, and had two sons, my husband Dan LeRoy Reinhardt, and his brother John. So your mother's cousin is actually my father in law.
I married Dan, I have one daughter from a previous relationship, Tara Anne Leek-Wilson. Dan and I have two sons together, Cian Timothy LeRoy Reinhardt and Aiden Connor Reinhardt.
