Tracing the FRANCKE surname

Dear Listers
I have researched the FRANKE name and have traced 11 generations from 1660
until the present time in my direct line. They were from Baartz [Baarz] in
the Lenzerwische, Westprignitz, Mecklenburg [formerly Brandenburg] Germany.
I am now interested in locating collateral ancestors and any other
information that may lead me back to earlier generations. I received the
following information from a genealogist in Lenzen who researched the records
in the Lutheran church in Lenzen for me.
