Have been slowly wading through all the William Ashton Census records. The most intriguing is the
1841 where he is also a Painter (like Amy Ashtons death cert). They were living seperately, he in Macclesfield, Stockport, about 12kms away for Cheadle. Strangely he was living with 15 yr old Elizabeth Wilson & his apprentice John Beswick who's age I cannot read.
1851 Census, assuming he's the only single one, was living in Cheadle, Stockport with his sister Ann & niece Fanny as a cotton mill manager born in Stockport.
1861 Census, assuming he's the only single one, was living in Heaton Norrris with his sister Ann (age 63) & brother Joseph (age 67) as a gas regulator manufacturer born in Stockport.
Can't find any that say he is a widow however because he is always head of household. It is entirely possible that he remarried and changed profession after Amy's death. There is one census of Cheadle where he was living with John & Sarah Toping and married to his daughter Elizabeth with John's grandchildren Joseph (age 6) & William (age 4). William is a factory hand & they married in 1849 in St Mary, Cheadle, Stockport.
