My Grandfather (Benjamin Harrison Aires) was born in Baltimore. My dad used to tell me that he was one of 17 brothers and sisters. The boys were named after presidents. He moved to Pittsburgh around the turn of the century and became a civil Engineer. He was born in 1888 and died in the 1970's. I'd like to find out about the rest of that family, as my father and grandfather has passed away. And I don't really have any other way of connecting to that part of the family.
