Hello - late to the party and also came here via Google. I'm looking into John Sanderson from Nottinghamshire and it seems he was court-martialed for desertion and "losing his necessaries" (a researcher on another forum just pointed me in the direction of Fold3 where the record is for October 1823, shortly before he was sent on the ship to Oz). Was anything conclusive ever reached about John's parentage? Trees on Ancestry seem to assume Matthew and Frances (he had a son called Matthias as already established further back in the thread) and also a later daughter called Frances (Fanny). I still can't find a record of his time in the army though and the transcription on the court martial seems to read "Grand Guards 2 Bd" which to me is probably Grenadier Guards, 2nd Batallion??
