Hi Miriam,
It's nice to make contact with new relatives.
From what I know, Eliza Collins died before 1911 (as I couldn't find her in the 1911 irish census.

I have made contact with someone last year who comes from Thomas's daughter Mary, so they will be more closely related to you than me. I think they still live in Ireland.

My g grandmother (daughter of Margaret Shaughnessy, sister to Thomas) and her 3 sisters came to New Zealand in the late 1870's (although there are some relatives still left there from Margaret's 2nd marriage).

My email address is clairemfalvey@hotmail.com if you would like to ask anymore questions. I would love to know what you find at sixmilebridge....it's a little far for me to travel to (although I have been briefly to Ireland...sadly before I had really started doing my tree and missed quite a few places that I would now like to travel to).

Claire
