my family of Gallatins are also from San Francisco. I found out today that my g-g-grandmother Mary Gallatin was the daughter of Willis J. and Lizzie Gallatin. Willis and Lizzie also had one other son according to the 1880 Census named Willis E. Gallatin. I wonder if Willis J. could be related to your Charles Gallatin because one of Mary's children was also named Charles. Lizzie was born aprox. 1854 in Massachusetts amd Willis J.was born aprox. 1850 in Pennsylvania and worked in Gas Fitters. Maybe this is a shot in the dark but Gallatin isn't a very common last name, so any info you have would be apperciated.
