Hawkins Family and Friends in Pittsburgh in the 1950s (part one)

I am posting a series of family photos I have come across as I am going through family artifacts in our old home. These first photos were probably taken in 1955 or earlier. They consist of family members (I think) or certainly friends of the family. My father probably took most of these photos. I don't recognize anyone in them but they do seem to suggest something about social circles of African American professionals in the City of Pittsburgh in the early to mid-1950s. I note the clothing worn (even on casual occassions), the housing, and the sense of group co-operation that provided a social network that was mutually supportive.
