Question: I came across a curious occupation for my 53 year old ancestor in Manchester, England on the 1891 Census. I am not entirely clear what he did for work with the occupation of "Mill - Apron man"?
Answer: The occupation of an "Apronman" was that of a mechanic. In the world of industrial Manchester, England I am sure your ancestor was employed in one of the mills as a mechanic in the 1890's.
