I have a couple!
Ann (Dawn) Paulson, an Artist in Mansfield in Victorian times, and later in her career went to Australia. She had paintings exhibited in The Great Exhibition London, in Paris and in Melbourne. She was the niece of my paternal great grandmother. She was also a teacher of art when living in England, and some of her pupils when on to become well noted! When reading a book about her, I discovered that my great grandmother, the little woman on my avatar, had left home, and eloped to marry my great grandfather! Hence the signature line on the avatar - My Runaway Bride!
Bill & Boyd, - A popular 1960's duo in New Zealand, who later also went on to become successful in Australia. Friends from College days, their cover versions of hits of the Everly Brothers made them very popular. Then later composed their own, always topping the charts. Both their real names were William, one Bill Robertson and one Bill Cate. Bill Robertson used the name Boyd, obviously they couldn't be Bill and Bill! The name Boyd that he chose, was the ancestral name of our maternal great great grandmother - our ancestor in common, Elizabeth Boyd. We lived in the same area, and the families were all friends.
James Alexander Jamieson, Engineer of Canada, responsible for designing the Wheat Grain Elevators in Montreal, Canada, and other engineering feats. He was my paternal great aunt's Husband.
A few other marry'ins who have been quite prominent in the Anglican Church in Ireland and Australia - and just today found another, who is living in Wales.
