Walsh's from Galway

[v966732]

Trying to find any information on Thomas Walsh.

He is listed on the England 1881 Census as living in Charles Street, Bishopwearmouth, Durham, England. His place of birth is given as Galway, Ireland, and his year of birth abt 1843. He married Eleanor(Ellen) Fransway and their first child Maria was born in 1878 (they had 3 other children James, Henry and John).

His brother Henry was also living with them and his year of birth was given as abt 1853 with his place of birth Ireland.

On the 1891 census Thomas's year of birth was given as abt 1845 but in the 1901 census it was 1843 again.

I can't find any reference to him in England prior to 1881 so I am assuming that he left Galway sometime between 1871 and 1878.

I would be very grateful for any assistance anyone can provide.
