That's interesting regards reason of adoption of Fletcher name by George and the trade tradition continued. George's son Percival (Percy - my great grandfather) and his son Jack, my father, were both boilermakers at Cockatoo Island also.
Can you advise I am on the right trail in that the George Holmes line is then
John 1795-1865 and
Samuel 1758-1838 then
Jedidiah 1720-1800 please ?
