Hi there, You got me at a good time - I was home with my mother who is a keen family archivist.
LAncelot Turtle (died 1828)of Aghagallon, Lurgan had 7 children. Mary Turtle is his daughter who married Joseph Shaw. Mary and Joseph Shaw's children were Jane Maria, Margaret, Lancelot and Sophia. Sophia married a man called Whiteside - that's all we know. We are also from the Aghagallon line of Turtles.
The first Lancelot Turtle that we have a record of - was Lancelot Thurkilld who was 1st Marquis of Hertford. The Lancelot that we have been discussing is his Grandson. Contact us if you need anything more - we'd be delighted to help.
