[Ger-Poland-Volhynia] Kowalewko Plock

[K. Gallagher]

I have been trying to locate a birth/baptismal record for my  
grandfather, Adolph Schulz, born in the 1850s in Kowalewko, Plock to  
Carl and Wilhemine (Schulz) Schulz.  First I tried the Evangelical  
Lutheran parishes surrounding Kowalewko: Plock: Mlawa, Sierpc and  
Plonsk but did not locate the record or family.  Then I found a  
reference on-line to a Reformed Lutheran parish in that town.  This  
would be possible because the birth records of three children of his  
by his first marriage are in Reformed Lutheran films of Klein Gluscha,  
Volhynia.  However, the records available for the Kowalewko Reformed  
Lutheran parish referenced start in 1870, well after my grandfather  
was born.  Does anyone know where I can access Kowalewko Reformed  
Lutheran records of the 1850s?
