Ammanda, I have John's Military Service Records - he enlisted at Cueta, Africa 25 May 1810 at 15 years of age. His service ended on 8 Feb 1837 in Australia. From 5 April 1819 until 1 April 1826 he served in the West Indies. He was a Sergeant for 8 years and 55 days and Quarter Master Sergeant for 5 years and 106 days.
I was looking for their marriage in Portgual/France, so that information, although unsubstantiated, is news to me. Thanks Julie
