Richard,
John and wife Mary Doherty live in Keenagh during the Valuation. Children I have born to them are:
1858 21-Nov Mary John McNulty Mary Doherty
1858 Jan MARRIAGE John McNulty Mary Doherty
1860 March Pat John McNulty Mary Doherty
1862 April John John McNulty Mary Doherty
1864 May Peter John McNulty Mary Doherty
1868 July Mich John McNulty Mary Doherty
1870 Nov Honor John McNulty Mary Doherty
1873 April Cath John McNulty Mary Doherty
I have no Terrence or Francis , Peter, McNulty births that early. nor any John McNulty and Honora giving birth to any children.
There is a Peter McNulty and Bridget Nelson living on Rake st having children in the early 30s & 40s. Thery married in 1833. Also a Pat and wife Sara Nelson (most likely siblings marrying siblings.) also on Rake st who married in 1838.
Perhaps they lived along the fringe Crossmolina Parish, but went to another parish church such as Moygawnagh, Addergoole, Kilfian, ect.
Also tried to link the siblings of John, Mich and Mary but made no connections.
Infortunately the register is missing pages, and entire months and years so it is not complete.
Sorry I couldn't help,
Diane
