Search for Zacharias Pfingst born in Biskupiec (Bischofsburg)

My name is Kathy and I am looking for any information about my family member. He was born in 1797 in Biskupiec. His wife's name was Grabriel before marriage to Zacharias.

You might want to look for the protestant church books of Bischofsburg, Ostpreussen, Kingdom of Prussia. The LDS has the relevant ones on microfilm:
