Werner was the photographer at 1227 Market St.San Francisco
Aunt Minnie and Arthur Cornelius
Thanks for stopping by.
Update from Jacqi:
Arthur's middle initial was F., and he was a musician in San Francisco. While I couldn't find any entry for him in Find A Grave, an obituary mentioned he was the son of Mrs. Minnie Cornelius and a native of California. Minnie and Arthur appear in the 1920 Census.
