I'm pretty sure that John from Churchill is a different family.You may want to look for the family that had the Devlin Funeral Homes.They are not related AND I'm pretty sure they are from the Churchill area.
My family is from "the Bluff".All the land that Duquesne University and Fisher Scientific are built on used to be were the Devlins and Hoopers resided.As a matter of fact, it used to be Hooper Brothers brickyard and a street near the Civic Arena was named for my great-uncle Pat Hooper (until the City chose to change it).
Thanks for responding. Good Luck with your search. Mary Lou
