on my family, research was a pain due to mis-spelling the family name, anyways, I found a Jacob Harle in 1841 census, born at Somerset 1796 so aged 45, wifes name Sarah aged 50 born at Somerset, & son John, living at Milton, Kewstroke, is this a possible match?
not found any military yet, though in 1841 states this fellow as being agricultural labourer
