Hi Geoff Abernethy Higgs I am married to David Stokes Abernethy, son of George Stokes Abernethy who may have been related to your mother Hazel. I have this information from my now deceased mother-in-law, Molly (Mary Margaret O'Meara) and from David. Molly and George married in Mt Isa and had two sons, David Stokes and Glynn Paul. I believe that George's mother's name was Rebecca and I think his father's name was William. George left South Australia after his mother died. George and Molly went to live in Brisbane in the mid to late 1950s. Paul still lives there. David and I live in Townsville.
The story I have heard is that Rebecca Abernethy was Rebecca Stokes an adopted daughter of one of the Lloyds of London family. My understanding is that at least some of George's siblings were Geoffrey, Hazel, Ona. There may have been others.A cousin of my husband's Dawn Abernethy wrote a family history about nineteen or twenty years ago.
We have no detailed information other than this, although Paul may have more. We haven't seen the family history, I don't even know if it was published. Beth Ward (nee Abernethy), George's niece in Adelaide would know about it. Regrds
