I have looked in the 1841, 1851 and 1861 censuses of Hunts on the Ancestry.com site, using the free access at my local library... that led me to John Peacock, b. 1829 in Spaldwick, Hunts, and to his parents William and Elizabeth Peacock... the 1851 gives the birth parish for them all, so that is the clue i have used to look further in Spaldwick, Tilbrook and Buckden (her b.place). I don't have quick access to the parish registers, but may eventually get info from them. I have family in Salt Lake City near the Family History Library, but they are very busy working on the project to index the 1940 USA census, which is being released next month online... eventually we will get to the registers for more info on the Peacocks...
It is good to see that cousins are also interested in the UK.
