Jenny, There is a strong possibility that O'Callaghan families around Kilshannig are linked. Your findings indicated that your Kilshannig family were landowners or did they transfer the lease for land. My Cornelius was unable to read and at the time of his enlistment into the army in 1846 in Mallow aged abt 23. I suspect that it is the same Cornelius that is recorded as distressed in Mallow in 1846 and that his family were victims of the Famine. He was unable to write and was a labourer when he enlisted which raises questions about his family and the ownership of land. In 1846 his family may well have owned land but met hard times and lost everthing. I have spoken to a local O'Callaghan and there is an interest in conducting some local research. I intend to return to Mallow next year and hope to find some information about Kilshannig cemetery. There are some later O'Callaghan graves there and I was informed that a local lady had information about the churchyard. ] After enlisting, his name was recorded Callaghan which remained until after his death in 1873 and so my search grows. A while ago I found an Ed Callaghan from the USA researching (O) Callaghan and I am trying to locate him as his family came from Glantane, Kilshannig. Many thanks Richard Brisbane - AUSTRALIA
