I don't know if these will help but I have located the following:-Thomas Murphy married a Mary Ellen Bryan in
1891 in Bridgend Glamorgan.
On the 1901 census there is a Thomas Murphy aged 30 living in Maesteg Glamorgan with a Mar E Murphy aged 50.
These may of course be another couple.
As regards Thomas unless you know his date of birth and place he would be very difficult to trace. If he was born in Ireland it woukld be a problem as most of their records were destoyed by fire. Let me know if you have any further info
