It would sure be nice to put a name to the request. In the biographical history of Lancaste rCounty by Alex Harris there are NO Gaines or Gain listed but one Groh , C.L. elected a County Commissioner in 1831 also none by name of Kroh here. In Biographical annals of Lancaster Couinty there are none of any of your names in the Index in vol II there are two listings for the name of Gaines, none for Groh and none for Kroh In vol 3 none of any of the names in vol 4 again nothing I would say these would not be sources for your search for your names Joe Wolfe
