Patrick Ryan, (Mount Mary? Galway) and Mary O'Donnell (Mayo)

 My ancestor is  Patrick Ryan (circa 1829-31) who lived in mostly in Walsall, Staffordshire and in Rochdale, Lancashire for a few years. The 1851 census in Walsall has his birth place as Mount Mary, Galway. His mother Catherine (circa 1800-1805), was also living with him until her death in Walsall in 1865. The death certificate names John Ryan as her husband but I have found no records of him in England. Patrick married Mary O'Donnell in Walsall in April 1850 and had (at least) 8 children some of whom appear to have stayed in Lancashire and others moved back to Walsall by 1881. Mary's birth place was recorded as Mayo.

I have searched extensively for anything other than the 1851 census to verify Patrick's  birth place and would love to know if any other relatives exist. I have been unable to find anything further about Mary other than the marriage certificate that records her father's name as James.

I would very much appreciate any help or guidance,

Jane (Ryan)
