Thanks Brian, I went back to my Ancestry tree yesterday and was thinking I was going mad as I couldn't find the marriage on calverley.info again. I hadn't made any note of the marriage there either. This then must have been Charles second marriage as William was born in 1819 and Thomas in 1821, Mary 1823, Ann 1825 Maria 1831. So this means that Charles, Harriet and Susannah may well be the only children by Mary Hornby.
William and Mary had , Charles Henry (my Gt gt Grandfather) a combination of his and her fathers names, William Thomas (is this a clue to gt Grandfathers names?), Mary Jane (is this after step-mum and Mother?), Smith Gill (Mary's Mother was Hannah Smith) and Nancy Hannah.
Brian and Dave, I like the idea of looking at the bigger picture on this one. I've trawled all through Cudworth's books and can find definite links to many of my other family lines that show established links to the areas for generations back, but my Holdsworth line just seems to appear in the area in 1841. This family line wil disappear with my generation, because my Dad is the last remaining Holdsworth and he only has girls.
Cheers,
Jill
