Thanks for your response Dinny. Unfortunately I don't have a lot on Sloan Bolton. All I know is that he married Nancy Pollock, daughter of Thomas Pollock(b1909) who was the son of Robert Pollock (b 1865), son of Smyth Pollock (b1828) son of Robert Pollock (b 1778). At least that is according to the information I have collected so far. I tend to believe there must be a generation between the last 2!. They are my husband's line and emigrated to Australia around the 1850/60s. They appear to based around Drumoolish, Tamlaght O'Crilly
My interest in the Sloans comes from Thomas Sloan (b 1800) who married Margaret Irwin (1806) whose daughter Esther is my GG Grandmother. I think Thomas came from Moneygran. Esther married John McNeill, son of Abraham who is buried in the Kilrea Church of Ireland. There must be some link between the families as Lizzie Boggs, who came from Ireland in 1907 and married John Pollock ,stayed with the McNeill family in Sydney when she first arrived in Australia.
I have been in contact with other descendants of the McNeills who came to Australia, but we haven't been able to solve some of the problems - like what relation was Thomas McNeill to Abraham McNeill - their graves are adjacent in Kilrea church of Ireland.
I hope to come to Ireland next year, hopefully to find some answers, although I fear they may be lost in the mists of time!
Any assistance would be most welcome - it is kind of hard trying to sort all this out from OZ!
All the best
