Sorry to rain on your parade, Greta, but the Wargrave PRs have these burials:
26.3.1752 Richard Thrift
18.4.1762 Richard Thrift
Unfortunately, there is no additional information given, other then the name, but it would seem likely that in both cases they are the burials of the Richard Thrift baptisms which Kim has given you.
Also, I have Friths in my tree - plenty around this area, mine are in Great Marlow, about 12 miles from Hurst. Infact, one of the Frith wills I managed to obtain was actually headed THRIFT alias FRITH. It might be worth looking out for Friths as well - just to add to your burden!!
