Hi Heywood,
Thanks very much for looking into this for me. Yes, looking back at my post, I think I did perhaps overload the info a bit!
Here's what I have so far...
1857 - St Chad's, Manchester. Michael Hinds, 38, widower, labourer, of Hanover Street, married Mary Foley, 20, spinster, also of Hanover Street. Michael's father was Patrick Hinds, also a labourer. Witnesses John McCann and Ann Hinds.
1859 - St Chad's, Manchester. Thomas Shevnan, 22, batchellor, dyer, of Bosdins buildings, married Mary Nadin (Navin/Naven), 19, spinster, of Cock Gates.
1861 Census - As you can see Thomas and Mary Shevnan are living at Bosdin's Buildings with their son, John, nine months. Michael and Mary Hines also live here with their children, as do Patrick Navin and Elizabeth Navin (nee McCann/McGann). Patrick is Mary Shevnan's brother. They are both listed as being from Ballintubber, Mayo. Thomas Shevnan and Michael Hynes are listed as being from Mayo. I can't find William Kirby on the 1861 census.
1863 - Thomas Shevnan died at Manchester workhouse. I think his daughter, Mary, later went to live with William Kirby, who then brought her up as his daughter, which would explain why she is listed as such on the 1871 census.
1866 - St Chad's, Manchester. William Kirby, 32, widower, labourer, of 14 Back Hanover Street, married Ellen Muirhead, 26, spinster, also of 12 Back Hanover Street. The parish register says his father, Patrick, was from Mayo. Witnesses were Robert Foster, of 10 Back Hanover Street and Anna Hines, of 12? Back Hanover Street.
1867 - William Kirby's son Michael is baptised at St Chad's. Godparents Timothy Fraley and Maria Hines.
1869 - William's daughter Mary is baptised at St Chad's. Godparents Michael Hynes and Maria McGann.
1870 - Michael Hynes and Mary Foley's son John Hynes is baptised at St Chad's. Godparents William Kirby and his wife Ellen Kirby.
1871 Census - I'm still trying to find out who Mary Mean is. Perhaps she is Mary Navin/Naven and its a misspelling. What do you think?
1871+ Catherine Shevnan is godmother to the remaining four of William's children. Michael Hynes is godfather to one of them. John Hynes (the one born in 1870) is living with William on the 1891 census and listed as his nephew.
In answer to your query about Michael Hynes's two older children, I have found Patrick Hynes baptised at Ballintubber/Burriscara in 1843 and Anne Hynes in the same parish in 1846. They both had Winifred Mannion listed as their mother. There's obviously a connection between these families, but I can't tie it down. Perhaps William's first marriage is the key, but I can't find it in Mayo.
What do you think? Hope you can help.
Very best wishes,
Dean.
