Hi Cassidys17
I just noticed you wanted the occupation's,the Cassidy's were all cattle dealers and William Cassidy as far as i know had a farm,and as the family story says the farm was were the pennyburn school is know,i think the bishop bought the land from the family at some point.They also had a butchers shop,not 100% certain but i think Margaret Doherty was from the Doherty families who were well known butchers in derry,i don't have any proof of this though.Mary Carr came from Faned Head in Donegal and could speak and read and write in Irish.I have a photo of Wiliam and Mary's headstone,they are buried in the city cemetery Derry,William died in 1928 aged 70 and Mary died in 1920.Wiliam's son's were all cattle dealer's as well.Are you decended from Denis Cassidy.?.
