hello, i have o'connell's in connecticut, too.my ggf was michael o'connell, born 1861. he had a brother john, they came over around 1882. i do not know michael's parents.
i wonder if you have found the siblings of thomas since you posted in 1998? any help appreciated.
i have a lot of unidentified photos, there are several group pics, and there are several with an old lady, not just a little old, but like 70's 80's. i would be glad to share if it looks like a connection
thanks for your time.
