Thanks for your help. I hate to admit that I am not related to you or Wendy. I committed a cardinal error by taking the word of someone else. Your posting made me realise that I hadn't checked information I'd been given years ago. Yes I am descended from a Mary Ann Dando but her father was William and not George. I have major deleting to do! It's taught me a valuable lesson - CHECK EVERYTHING.
Sorry to have wasted your time.
I do have a birth certificate for the Mary Ann belonging to you which I'm attaching. I hope it's of use.
