YES, that's my tree! I've found out a lot more since then... My Great Aunt Lesley (Fulton) must have posted it to your Nana, and they are cousins. I'm descended from Sarah Heron Wyinks & live in Whangarei so doing family research in Dunedin is not an option for me at the moment! That's a great idea to develop something for your Nana! I have some photos of her in which I'm not sure which is which sister! I would love to share information... Have you seen my family website at http://www.turnerwhakapapa.com
You can email me directly at shelleychapporyATymailDOTcom & we can swap photos & details...
