Ken,
Thanks for the help. I was able to get a copy of his discharge papers from Kew. I assume that this would be the same as listed in Ancestry and Findmypast. I must check those out. Interesting that Ancestry has him in the 'Canada' records.
I always assumed that Samuel was illiterate because he was never promoted in rank. His discharge papers give no indication of disciplinary problems. The prime requirement for promotion was literacy and numeracy. After 20 years, with no discipline problems, he retired as a private soldier.
