Hi Lois,
I have also lineage FN Pieck. But I am searching in Stallupönen for them.
Stallupönen is near by Pillkallen. I have this marriages (direct lineage):
Father: Johann Pieck oo Ana Barbara Laser
Son: Johann Pieck *21.11.1766 in Mehlkehmen + ? oo ca. 1792 Ana Maria
Loebel *about 1771 + 29.05.1795 in Germingkehmen
In Tilsit there should be (www.familysearch.org) lineages with the name PYK,
but until now I only look in Stallupönen for the PIECK lineage.
Greetings
Angela
