Huntingdonshire is a good bet...My 3rd Grt Grandfather lived in Earith his name was 'Phillip Bedford Bonnett' He was born in Earith, Huntingdonshire in 1869 and Baptsed there in 1874, and In 1871 was living in Bluntisham cum Earith with His parents John and Sarah Ann Bonnett and his 3 brothers (Sarah's maiden surname was Bedford and that is where he got his middle name from)
John Bonnett (Phillip's father) seems to have been living in Earith in 1863 as his 2 sons John and Robert were baptised there but there is no Bonnett's in Earith/Bluntisham cum Earith before 1863 as I have the parish registers going back to 1538. But where John Lived beforEarith I don't know...He was Baptised in Ely St mary's like I said and I have the Cambridgeshire census 1841 CD but Because it hasn't been wrote out it is just photos of the census records so there is Dirt/Smudges/Ink Spots so In some places hard to see but I know he will should be on there somewhere and maybe his father John as well
