Looking for info on George Johan Erhart and Margaret Hillick, married about 1850. 3 sons: John Columbus, James Wilson, and George William. My GG Grandfather was John Columbus. Erharts were from Germany, Margaret Hillick from Ireland. 1860 census shows them with his father, children, and 2 others. I don't know any more than that. John Columbus went to San Jose, CA, James wilson to Northern CA. I have one old picture of George Johan, and a protrait of John Columbus family.
