Roger,
Let me begin by thanking you for your time and effort researching the Keohane family!
I reviewed the census records and compared them to what I have. I found birth records for Timothy (1865), Michael ('66), John ('67), Denis ('68), Jeremiah ('71). All were born in Courceys. Thomas was born 1873, Catherine ('75), Ellen ('78) and Cornelius ('73) all in Kinsale. The ages of the children do not quite match with what is recorded in the census. I do not have a Hannah in my records.
What I found recently was that Thomas was living in 1900 with a James Keohane in Boston. James was born 25 Sept 1867 in Clonakilty to Timothy Keohane and Mary Donovan. In the 1906, Thomas, another Thomas, Cornelius, James and Denis Keohane are all living together in Boston. I've been unable to find records on Denis after 1906 and wondered if he went back to Ireland since his name does appear in the 1911 Irish census.
Is Ringrone Parish, Courceys and Clonakilty in close proximity to one another? Are they considered to be part of Kinsale? My hunch is that James Keohane's father Timothy may have been a brother to Cornelius Keohane. James died in 1912 and his widow and daughters lived in the same house as Thomas. There most probably was a family connection which makes me wonder if Cornelius Keohane was from Clonakilty.
I'm certain that I confused you as I'm quite confused myself. This is my first attempt in researching Irish ancestors. It's quite challenging!
Again, thank you for your help!
My best,
~Susan
