Esther's residence was actually Crohane East, parish of Desertserges. It has turned out that the information about Robert Bennett & Esther Kingston and their children produced by this thread is pretty much correct.
During our visit to Clonakilty we visited the farm in Crohane East where Esther Kingston was living (and most likely born) before she married Robert Bennett in February 1846. Farm presently owned by a descendant of Thomas Kingston, Esther's brother.
We also visited St Mary's Church, where Robert & Esther married.
We met descendants of Mary Bennett Nagle, of Thomas Bennett and Mary Clarke and of Hester Bennett Deane. We had a wonderful morning tea where we met many third cousins from the Clarke, Deane and Buttimer families. We have also connected with descendants of Thomas Bennett and Martha Sebury who live in USA.
We also met descendants of Abraham Bennett and of his brother Thomas Bennett of Ahamilla. We visited the Agricultural College at Dararra, formerly a farm owned by Abraham Bennett and then his son John Bennett.
It appears that James Bennett was a brother to Robert as records show James' farm was transferred to Robert.
We also visited the cemeteries at Kilnagross and Kilgarriffe.
Highlight for me was the visit to the old Bennett farm in Kilgarriffe where my g grandfather Samuel was born and grew up prior to immigrating to Australia in around 1885. Appears that Samuel was the youngest child as his age at death is confirmed as 39 and not 46 as previously reported. This make his birth in 1864.
We were also given a photo of Meta Bennett's wedding to John Bennett of Kilmoylerane in 1912. This photo is believed to have been taken at the Bennett farm in Kilgarriffe. Of significance is that 4 Bennett families attended this wedding, Bennett's from Kilgarriffe, from Kilmoylerane, from Ahamilla and from Fourcuil. Henry Sebury, presumably Martha Sebury's brother, was also in the photo.
The information produced by this thread has proved significant to my family history research and I again thank all contributors for their assistance.
