When Ethel married Frank Brown at the South Coast town of Wollongong in 1901, one of the witnesses was Henry Parsons.
Then Ethel's first daughter, Thelma Violet, married a George Parson in 1918 at the South Coast town of Moruya.
She married under the name 'Violet Governor', not Violet Brown.
The Parsons couple had four children, Cyril, Ethel, Robert and Ruth.
A report I found on the web about the significance of the Biamanga & Gulaga mountains of the NSW South Coast, published by the Aboriginal Cultural Association and others,claims that an Englishman, Samuel Parsons had a son Daniel with a Wandanian woman called Sally.
He may have been the forebear of the Parsons associated with Frank and Ethel Brown.
The report also contains a photo of a Cronjy Parsons ('Sonnoboy') as a member of The Leaf Band at Lake Wallaga in 1922.
In 1873, a Henry Parsons married Dorcas Stumbles at Wollongong.
In 1877, they had a child, Henry M Parsons.
Either may have been the witness of Frank Brown b.1878 at his wedding to Ethel Governor in 1901.
However, it seems it may have been the younger Henry who named his first child, a girl born in 1902, Ethel.
