I have in my data base a Robert Brock. My notes show that he lived in Killymore, County Fermanagh. He emigrated in May 1849 to
Adelaide Twp, Middlesex County, Ontario. My sources are 1) a Rootsweb page of Lawrence Hugh Boyd, and 2) a book titled The Descendants of Thomas Brock of Killymore, Co. Fermanagh, Ireland,
Author: Robert Grant Espie, West Hartford, Connecticut, USA
Publication: June, 1991.
I haven't looked at this for a long time but I suspect that the book is cited by Boyd on his webpage. I don't have a copy of the book in my files. That is all I have unless you are interested in the descendants of Robert Brock because they lead into my family. A son of Robert is named Thomas so that is a possible indication that there is a connection between Francis Brock and Robert Brock. Happy hunting.
