hi. i see a possible army record for an ancestor thomas pritchard. he was born in 1782 in oswestry and married in oswestry in 1804. first child thomas 1805 d 1806. second child 1807. no other children found until george in 1814 b just over the border in wales. i think the gap could be because he was in the peninsular war. and one of the moderators Garsonite on roots chat found a record in 1811.
