Have found a bit more evidence supporting the idea that James Hutchinson and his family changed their surname to Richardson, but they did it some time after 1841.
1841 Census Elton, Warmingham
James Hutchinson aged 40 Ag Lab bCheshire
Wife Elen aged 35 bCheshire
Children Charles aged 7, Hanah aged 4, Elen aged 7 months
Also John Hulme aged 18
1851 Census Warmingham
James Richardson aged 52 Ag Lab bDarnhall
Wife Ellen aged 48 bMoston
Children Charles aged 16, Elijah aged 7, Mary aged 5.
Also William Hulme aged 62 Retired Farmer
No christenings for James Richardson in Darnhall, Over, or Whitegate 1798-1802
One christening for James Hutchenson at St Chad's, Over, father John Hutchenson 1799
Am I worried about the Hutchinson, Hutchenson, Hitchinson variations at St Chad's? Not really, the christenings with John H.... as father don't clash. I just suspect the handwriting is tricky to read.
Not proof, but the evidence is stacking up.
The marriage of James and Ellen is a bit mysterious - the only candidate I have is in Warmingham in 1821 to Ellen Steele - which is 20 years before the first census, and can't see any children before 1834. Its a little odd.
