I have a 10 page letter written by an elderly Killarney Hilliard to my father giving many details of his family. I believe his name was Dick and the letter was written before 1956. His father was John. John's father was William, Willaim's father was William and his father was Robert William, his father was William and his father was Captain Robert (came to Ireland in 1649 and married in 1651).
I am not skilled in matters forefatherish but I will be glad to send you a copy of the letter. It is an interesting history of the family in Ireland and the author shows himsef to be a scholar and an excellant writer. Captain Hilliard's family was from the Holderness Peninsula in Yorkshire.
