Mary Jane (Ingham) Dean, Margaret (Dawe) Ingham,
son John Ingham "Jack" Dean?  or son Joseph Henry "Harry" Dean?
baby Helen Dean? or baby Margaret Foulds Dean?

The son's and baby's names are guesses based on who had children before Margaret (Dawe) Ingham died in 1909.
If you can help identify the son and / or the baby in this picture, please contact me.  Thanks!
