I have traced my ancestors back to John Clift, father of Richard Shuttleworth Clift. Using information from posting here I have found an 1841 census entry for Jno Clift, a Currier, married to Rebekah Clift with three children, Richd, Hy and Anne in Ipswich, Suffolk. I have also found an 1851 census entry for three brothers, lodgers, by the names Richard Cliff (note the spelling), Henry Cliff and Shuttle Cliff in Braintree Essex. The dates of birth for Richard and Henry are within a year between the censuses and Richard's is within a year of my findings for Richard Shuttleworth Clift.
I hope this may be of use after all the time that has passed since your original posting.
