Looking for help

Since your relations were still in Ireland at the time of the 1901 & 1911 Censuses and you know where they were born, you are in luck.

Cornelius Leary/O'Leary:
I didn't find Cornelius under O'Leary but found several Leary's in Leamyglissane. This looks like his family, including siblings, parents and grandmother in 1901. If you look at the actual census, it shows that the father was a shopkeeper.

Here they are in 1911:

Ellie Donoghue/O'Donoghue:
Same thing with Ellie's name. There are a few Donoghues in Shinnagh. This looks like her family in 1901:

Here they are in 1911. Note that there is a Kelleher brother-in-law living with them so her mother was likely a Kelleher. I didn't find him in 1901 however:

Looking at the children's names of Cornelius and Ellie, you might convince yourself a bit more that we have the right ones. The first son would likely be Michael and first daughter would be Mary. The second son would likely be Patrick and second daughter Catherine. If there are more children, you'd likely see some named after the siblings also.

Did you have any luck? Do let us know
