I am a Waddingham in Sydney. Our trees do not link "Yet" I have been trying to work that out.
Your Samuel (aka Geo) Waddingham died Vic reg#1898/4588 buried at Kew Cemetery 13/3/1898.(see Kew Cemetery on line)
Phoebe died Vic Reg#1884/4683 buried Kew Cemetery 3/4/1884.
If you like you may ask for other info on Waddingham, as I have collected quite a bit of info on them.
On Worldconnect(All one word) in line you can get your family tree. I lady in England has put in online. Your Waddingham's come from Osbournby, Lincolshire, Eng.
