I can't find my couple in Leeds in 1861. In 1871 they are in Hunslett Potter Newton 14 Union Terrace Jonathan Clegg 1823 Dewsbury Yorkshire occupation draper laceman, Betsy Clegg wife 1827 Torksey Lincolnshire. Betsy's maiden name was Bullivant. In 1881 she is widowed. I can find her in 1891 too, but although she did not die till 1919 I can't find her in the 1901 census either. Jonathan died in 1880 I think, certainly between 1871 and 1881. I've tried using Ancestry and can't get them. I tried the search engine for the 1901 census and think I got Jonathan put as age 40 in Hunslet but Betsy doesn't come up at all. If you can solve this puzzle I would be greatful.
