[Ger-Poland-Volhynia] Posen vital records mid 1700s

[Richard Stein]

I have a lead that my Abram/Kelm ancestors may have come from the village of
Galczynek, Posen province, and settled near Sompolno, Poland around 1785.  I
found Galczynek located about midway between Witkowo, Mogilno, and
Trzemeszno.  The earliest LDS microfilms for nearby Lutheran parishes start
in 1817 for Witkowo, 1818 for Gnesen, and 1835 for Trzemeszno.  Does anyone
know if there are earlier Lutheran records for this area and, if not, would
the people have registered their BMD in a local Catholic parish.  Galczynek
was in Rekawczyn Catholic Parish only two km away.
Thanks in advance for your help.
