There are published church record books for the 3 German churches in Massac Co, IL. I abstracted any information about German-born members. I have a listing from St. John's Luthern for a Carl Huenerkoch. He was born 8 Aug. 1807 in Lohe, Uchte, Kingdom of Hannover. He was married to Charlotte Schneidemann. She was born 23 July 1820, also in Uchte. There is a Sophia Maria Scheidemann born 24 Nov 1824 in Uchte, she may be Charlotte's sister (these were hand written records, prone to errors). Also from Uchte are a number of Kruegers (August, Heinrich, Karolina, Katharine, and Louise).
If this is the right Huhnerkoch (I know the spelling is a little different, but again, the church record books are translations from the original hand-written ones, prone to error), then Uchte is where you want to look. Unfortunately the Kingdom of Hannover hasn't let the Mormons microfilm their church records yet. You'll have to write to the church record office in Hannover to get a copy of Carl's baptismal record (I've been to the record office in person, let me know if you want more info).
