Definitely the same family as I have Elizabeth & Charles both on my tree along with their 5 sons but that's as far as I can go on the family, I have all of William & Sarah's children & grandchildren but apart from Mary I have nothing else .I have a photo which was Marys here with the family standing out the front of the family home, Mary is standing on the left next to her first husband , in front of her is her father with a small boy, on the photo it has the boy as being a Victor Phillips. If you like I can send you a copy of the photo I have, plus if you wish I can fill in Marys family downwards.
Very pleased to hear from you.
