Hello,
I recently found a site titled Poznan database, which had indexed the marriages for anna lonowska to Frank kowalski and Martinus Lonowski to Magdalena Grulepa/Grzulepa/Gzulepa in Chojnica parish, Poznan County, Poznan, Poland. I have since obtained access to the most recent microfilm for this parish from FHL, and have obtained the baptismal record for Anna, John and four siblings, and their father Martin, and the marriage record for Martin and magdalena. If you are related to me, would you like to assist me by looking at a neighboring parish identified by poznan database or a microfilm covering the next closest era please contact me.
