Allison,
I could not find any records in the LDS library pertaining specifically to Jenkau. But it was a very small village.
I did find these church records from a town nearby in the same time period. They are "Evangelische" which is what Germans call the Lutheran church. Do you have any idea whether they were Lutheran, Catholic, or Jewish? It is possible they went to church in another town, but admittedly it is a longshot. Taufen is baptism. Heiraten is marriage, and Tote is death. You can order this film from your local LDS family library. but you may want to zero in more.
