The ref to Mary Manion (1837) on the Wales 1851 Census now changed/corrected (?) to Marion. It was Manion for weeks.
Reference to Peter Mannion being the father to Mary Mannion (1838) is from a tree of which I noted. I have not searched it out myself, the tree used a reference to "OneWorldTree" which I cannot see any details. I'll need to do some sleuthing myself. Peter is noted to be from Killian Galway b:1814 & married in 1833 to Anne Heavy b: 1816.
I'm trying to locate family members, siblings, cousins, of "Mary" in order to try to match my Mary Mannion Cannon to a later Mannion family from Galway to solve a family link.
Mary appears on the England 1861 Census as Mary Cannon, now married to Michael Cannon (ex Roscommon) .. Married 1859 in Lichfield Staff where they had their children.
