I believe this Charles Frederick O'Connor was first married to Alice P. Warren and had 4 children (possibly only 2 survived: Charles & maybe Alice). Charles was also married to Anna Shepherd and lastly (I think) to Marie St. Cyr of Louisiana. I'm not sure which of the first 2 wives committed suicide (this family legend on our side is that she jumped in front of a train?). I've not found any specific documents to prove it. Alice possibly died in 1914 and Anna would have died bet. 1920-1924. I'd be very interested in exchanging info! Contact me at longtalsally@comcast.net.
