My great-great-great-grandparents David Gellatly and Catherine Tarvit were married in 1799 at Inchture, Perthshire. Catherine was from my native village of Cellardyke in Fife, and David became a fisherman there.
Catherine's sister Elspeth Tarvit married George Gellatly at Inchture in 1796 and it seems likely that David and George were themselves related, but I can't prove it.
For various reasons, I think David Gellatly was the David born in 1777 at Moneydie, Perthshire, to Patrick or Peter Gellatly and Jean McRobie (her name is spelt Crobie on their headstone in Moneydie churchyard).
I wrote an article about my Gellatly researches, called "In Search of Gellatlys", back in the 1980s, and it was published in The Scottish Genealogist.
If anyone reading this thinks they are descended from that David Gellatly born in 1777, and he had nothing to do with Cellardyke, I would be very interested to hear from you! I'm not convinced I'm right about his parentage and have an open mind.
