Name from Joshua Keijsers’ Family Tree as at May 2020.
Joshua is the x2 great grandson of Walter and Edith Minnie (nee Oliver) Chatterton through their daughter Beryl Minnie May Chatterton, and in turn her son Lindsay Jack Martin, and onwards.

Joshua Keijsers’ Family Tree has this Robert Oliver (father of Ian George Oliver) being, married to “Alberta Gates” who died in 1992. Brian of nzolivers wondered if this Alberta Gates is “Alberta Lilian Gates” born 1914 and already in nzolivers ‘The Tree’?

Brian concludes that this Robert Oliver, is indeed Robert Thomas Oliver, and married to Alberta Lilian Gates.

Although this ‘Robert Thomas Oliver’ is not blood related to Brian of nzolivers that he can establish, Brian is connected by marriages on both his mother’s side and on his father’s side:
1. This Robert Thomas Oliver’s wife, Alberta Lilian Gates, and Brian of nzolivers (through his mother’s side), are both descendant from Joseph Dodson born 1780:
