I am interested in the information you have on the Canty's from San Francisco...I may not be of any help to you, but it is worth a shot.
I have a Charles Michael Canty, son of a Thomas Canty. Charles was born in San Francisco, CA on 2 Oct 1879, married Dora Nagel in Portland, OR on 25 Feb 1915 and died in Portland, OR 28 Jan 1941.
This information comes from my 84 year old grandmother, who also lives in Portland. Charles would be her father. The only info she has on Thomas Canty was that he lived in San Francisco and died March 3 (yr??)
If this is in any way related to the Cantys you are researching, please let me know!! I am just beginning my family history and really don't know where to begin!! Thankyou! Rachel Hansen
