Grace MOYLE, born about 1790 who married James ROBERTS was the daughter of John MOYLE and Jane ROBERTS, who married on 27 June 1786 at Helston, Cornwall. I have no record of her ancestry back beyond that and cannot therefore tell whether she has any ancestors in common with Dorothy MOYLE.
However, I do have a record of the ancestors of Dorothy MOYLE, born about 1730, who married Anthony ROBERTS in 1756. Dorothy is my 2nd cousin, six times removed. I have her great grandparents recorded as John MOYLE and Elizabeth JAMES, who were married at Wendron, Cornwall on 22 June 1657. They were the first ancestors whom I share with Dorothy, and therefore (probably!) with you, Tony. They were my 7th great grandparents and, I think, your 8th, which would make us, according to my calculations, 8th cousins, once removed!
My branch of the MOYLE family emigrated from Mabe, Cornwall to Australia on board the “Prince Alfred” 150 years ago, arriving here on 22 February 1854, and settled on the Victorian goldfields at Ballarat. I happened to be born in Burnie, Tasmania when my father was postedfor a few years in the early 1930s.
