From a fellow Kiwi who married into the Ryman family in Australia.
The mother of my wife, Janice, was Norma Valmai Ryman, whose grandfather was Thomas Ryman. He came to Newcastle, Australia with his parents in 1855. The family came from North Hinksey and their origins lay in Great Tew, Oxfordshire.
Currently, Julian Rogers is keeping me up to date with details of the U.K. family, while I and others are working on the Australian descendants of Thomas & Susan Ryman, formerly of North Hinksey. Regards
