Hi there. I hope some of this information helps you. Charles Fairman b 1890 was my great grandfather. My father has told me that his grandfather (Charles) left Providence, Rhode Island and came to California to help map Catalina Island. My grandfather, Frederick Harris Fairman was born on 06-08-1897 in Providence, Rhode Island. He married my grandmother in Los Angeles in 1931. They had my father in 1933 and my father had me in 1967.
It sure sounds like you and my father are cousins. Small world so it seems.
It would be great to communicate with you further and see what you have found out in regards to the Fairman or Harris Family tree.
