Unfrotunately from the names you gave I don't know if there is a connection. I can
give you the information I do have. From family members I have:
John F. Zimmerman (1847-1925) married Mary Spences. They had a son David who married Rose
and together they had a daughter Agnes Ashby Zimmerman, and a daughter Mary Adeline
Zimmerman(1881-1975) who my Mom remembers as Aunt Addie.
John married again to Margaret J. Haverick. Together they had 5 children. Gertrude who
married Joseph Ruff, Mary who married Ed Keisling, Leo, Rose Elizabeth(1886-1888) and
Clara Cecilia, my great-grandmother. Clara married Francis Joseph O'leary.
On Clara's death certificate it says her father was from Mt. Vernon and her mother was
from Warsaw.
If you could find out the names of the zimmermans in the pictures I may be able to help
futher or ask other family if they know anything.
I hope this helps and sorry I couldn't make a definite connection.
