By GEORGE we found him!!!!
So today has been a day of break throughs and we finally found our ever elusive George JOHNSON and where was he - right under our noses!!
He was in fact buried in the Ballarat Old Cemetary with his first wife Philadelphia JOHNSON. Only 5 minutes from where my grandfather lives. We had ruled this George out as we thought the age gap was too great between him and his second wife Drusilla. However upon purchasing many certificates I found on one of George and Drusilla's children's birth certificates, Phoebe's in fact that she had two additional siblings Alfred aged 17yrs and George aged 15yr from a previous marriage and there it was!! the proof that linked George to Philadelphia. We now have to more links to investigate :) Who knows we may find some living relatives..
I just want to thank everyone in particular Jan and Roy who helped me with researching and giving me leads to follow up it really has been fantastic to find out the who, what and where of my family ancestry.
