I have both a Daily and O'Rourke in my family tree in Ohio also. Kelleys Island, Ohio. Mary Daily would be my g-g-grandmother who married Leonard Keating and had Margaret Keating (I was named after) abt. 1868. I am not certain these were from Ireland.
Margaret married Michael Augustus Leyden ("Mitchell", who I am certain was born in Ireland). He is my g-grandfather.
On Kelley's Island the followng Daily's were born:
Honora 1884 Catharine 1881 Annie 1874 John 1877 Bridget Ellen 1886
A brother of Michael, namely Patrick, married Bridget O'Rourke, I believe right on Kelley's Island, Ohio.
All of the Leyden's ended up in Cleveland, Ohio. I do not know if Mary Daily was ever on Kelley's Island or not.
So the names and places are similiar. Not sure how to tie them together.
