Yes I agree that Chiddenden is probably a variant spelling.So far we have found 38 different ways to spell Daniels and the number seems to increase whenever one of our lot does some research. Just about any vowel could be substituted for any other and consonants seemed to be reasonably interchangeable.
At any rate, my Chittenden reference is as follows: Nicholas Daniell married Elizabeth Chiddenden in St Mary Bredin Canterbury in 1650. Nicholas was at least 34 at the time and Elizabeth was his second spouse. She died in Little Hardres near Canterbury on 17/06/1668. These dates are taken from the actual registers at St Mary Bredin's and Little Hardres. The marriage entry also appears in the IGI(as Chiddenden).
As I said we have good reason to believe that the Daniels had moved to Canterbury not long before 1650. While we are not clear as to where they were before then, it does seem that it was either from North West Kent or from the area around Cranbrook,Cowden etc.
