As Debbie has said I do have many Crawcour relatives in Melbourne including Pat Coppel and his dad – they are all my blood relatives by and large most descended from Isaac Crawcour son of David ( David is my 4x great grandfather).
However, I also have my Hart relatives in Victoria- Grace Hart ( dau of Aaron Hart and Rebecca Crawcour my 3x great grandparents) married William Hanson ( his father was a butcher)- non Jew.
Grace died 1928 in Victoria.
The family are also still in Victoria. Also, David Hart married Sarah Simmons- David is the son of John Hart and Elizabeth Jacobs plus I have Simmons/Crawcour marriages- this line was in Sydney
Note all the surnames- you can bet there are closer family links.[Phil Kirby]
