I hope this reaches you since your message in Ancestry is a bit old. I believe we might be related. Felipe II born in 1800 married Ramona Pedrin born 1830, they were my great great grandparents. Their daughter Maria Sara (born 1853)was my great grandmother (I have her picture). One of her daughters, Amelia (born 1879-I have her picture) was my grandmother. I do know that the last name was originally spelled Montreuil. And like others, I only have info back to Felipe Francisco Montreuil born in 1774, wife Caroline. Because of some of the spelling changes, I bet we have many more family members out there. And your father's parents were Philip and Freida (I have their picture)? They are all in my family tree, although I'm sure there are lots of family names missing. Hope to hear from you.
