Yes, I have confirmation that your Catharina was b. on 2 Jan 1762 in NJ, the dau. of Georg and Barbara KRUMREIN.Her birth record was found in the Friesburg Emanuel Luth. Ch. Records which were published by the Gloucester Co. (NJ) Historical Society.
In 1990, my first article on Georg KRUMREIN was published in the PA Genealogical Society Magazine and they are going to publish myfollow-up article on the earliest records found for him in NJ by another researcher who is not a KRUMREIN descendant, but who shared this information with us.
The Mormons have filmed my KRUMREIN records up to the 1980's before these early records of Georg and his family were found and they are on six films that can be ordered and read at their main library in Utah or at any of their branch libraries all over the country.
Your Peter and Catharina (KRUMREIN) ZEPP's records are on Film #1597599.These only include a listing of their children and of the church records that I found in St. David's/Sherman's Ch. in West Manheim Twp., York Co., PA and in the Jerusalem (Bachman's) Ch. in Manchester, MD. I may not have a complete listing of their children.
