I was hoping for some advice
Catherine was my great grandmother, I know her father was called john from the marriage registration and according to the 1911 Census she was born in Sligo.
I am having some issues with dates. Both the 1911 Census which I am confident of and the 1901 Census which I am unsure of show her year of birth as 1883. The witnesses from the marriage registration could potentially tie in with the parents of the 1901 Census
However a death registration that I'm pretty confident of shows her year of birth as 1881
and a baptism registration which shows her father as John and mother as Bridget as per the 1901 Census is from 1880
I'm unsure if this is the same person or if I'm making a mess of this ancestor.
any input or advice?
