Hi again Paul.
I looked up the Parish Registers for Harlestone, Church Brampton, Gt.
Harrowden and found no mention of the name Stamp or Huet or
Kestins prior to the marriage in 1718.
Some of the registers (I think it was Church Brampton will re-check)
looked as though they had been eaten by a mite or something similar
as only half the pages still exist in the time span you wanted.
I looked from 1680 to 1700 for Edward Stamp etc but think they must have
come from other villages near by.
There were no burials after Mary Stamp, 10 May 1783 in Harlestone.
I checked to up to 1830.
I did find extra info to the marriages I previously mentioned so will list below.
