Hi Folks: I might as well jump in as well.Eliza Connell b.abt. 1836 who m. James Roycroft b. abt. 1829 of Kilpatrick is a sister of Hester Connell b. abt. 1844 who m. Edward Roycroft b. abt. 1840 of Kilpatrick.Edward and James are brothers.Elizabeth and Hester are the daughters of Richard and Margaret Connell of Prohoness.
The parents of Edward and James were Edward Roycroft b. abt. 1800 and Hester Wolfe b. abt. 1801.
Edward Roycroft b1864 is the son of Edward Roycroft and Hester Connell.He m. Sarah Roycroft b1865, daughter of John Roycroft and Eliza Bradfield.It is not known yet how the father of this John Roycroft (possibly Joseph Roycroft) is related to Edward Roycroft b1800, but they are in the right timeframe to be brothers or cousins.
There is one reference to there being two brothers who came over to Ireland about 1600 being the forefathers of all the West Cork families, so I agree with you Cathryn - there is likely a connection.
