Hi Howard,
Possibly but the earliest John Nobbs I have was born in Bedingham Norfolk in 1738 and married Elizabeth King on 15/9/1765 at Bedingham. The had about 8 children one on whom was another John born 1798, married 14/1/1823 Mary Watson. They had at least (prob more) 7 children and moved to Bungay Suffolk. They also had a John (b1828) but the line I am recearching descended from another of their sons Nicholas Hudson Nobbs b1830 Bungay, he was the one who moved to Yorkshire living in first as a page boy then a butler living in at the Parsonage at Spofforth where a total of 8 servants were kept. He married the kitchen maid Sarah Wilson on 1/1/1866, then had his own outfitting business in Ripon. They had 5 children all born in Ripon the oldest of whom was Robert Horace b Dec.qtr 1866, married at twice Elizabeth Kitson 12/6/1890 London, but split up straight away, baby born 6 weeks later Frederick (Clarence but Lawrence on birth cert) who was fostered out and eventaully adopted, Robert Horace went back to live with parents in Ripon. Frederick ended up in Bury and married there in 1914 and had two children Roy b1922 and Dorothy b1923. So the family followed more or less the same pattern as the one you are researching from Norfolk to Yorkshire, so perhaps your came down from John through another of their sons? I haven't found out what happened to all the siblings of the family yet. Hope this helps, if not perhaps someone will recognise it and get in touch with me?
