Further to my earlier reply, I have the family listed in 1841 on the 1851 water-damaged series, and, on the same census series, another William and Mary A. BAKER with a son, William at 24 Worsley Street, London Road, Manch. and, on a different series, a similar listing (William, Mary and William) with ages, but at 59 Garratt Street, Manchester. Lots of fun here...
