Hi,
I came across your posting and saw your interest in the Coye family name. The Coye family from Derryhoyle is actually related to me but our names are now spelt slightly differently. My name is Ronan Coy and I am from Kilchreest just a few miles from Derryhoyle. My Father used to spell his name Coye but we have all been christened with Coy (although my birth certificate says Coye). The name seems to have changed randomly during the past.
Their is a family of Coye's in Derryhoyle currently and Joe Coye is the father. Their are two sons Ciaran and Colga that i know off. My Father Michael Coy(e) is 4th cousin to Joe Coye. That makes me 5th cousin to Ciaran and Colga. When we were children we did visit each others houses on a number of occasions and their was a bond between the families as the name is quite rare. There was a captain Pat Coye from Derryhoyle who was a volunteer during the Civil war. He died in 1923 and was buried in Kilchreest cemetry. See the link
