We are actually having a Turtle Reunion in London in July! You should join! OK - I need to check with the historian in our family about this one - the location of the Turtle in question is absolutely correct - as Aghagallon/Tandragee area is the Turtle stronghold. My grandfather was also Lancelot Turtle - unfortunately I can't find the email trail from John Turtle (my cousin) - but will get back to you once I have spoken to him. 5th or 6th cousin? I know my 4th cousin, but that is as far as we have gone back! Sorry it has taken me so long to get back to you - have had a crazy year.
