A few more names to add to this family connection, via a contact from the Genes Reunited site. The contact is relaited via the Waldron side, and kindly sent me information from a book that was printed, no doubt from another Waldron family member.
Helping to fit the pieces to the puzzle, and I need to delve deeper into the Adams side to find out more. Haven't been able to find a marriage for Clarence and Evelyn - maybe I should search on the New South Wales records.
Evelyn's parents were Albert Samuel Waldron and Edith Emma Reynolds. They both worked at Newstead House - Samuel went to work there as a Coachman, looking after the horses and met Edith, who was a housemaid at Newstead House.
