In response to your query, I have determined that my grandmother Mary Agnes Mulhall was the second daughter of Joseph M Mulhall and Teresa Ann Mulhall (nee Burch). They moved from Elizabethtown Kentucky to Los Angeles California in 1912 to start a business building houses in the San Fernando Valley. In several family photos around about the time of the move is a dog "Spot" in each picture. I know they had 10 children of which five died very young. I don't have much additional information yet.
