[CROONAERT]

It all depends on the unit that maintained/started the original cemetery (some were more "germanic" in record keeping than others), whether these records were passed in completion to the kriegsgraberfursorge (if they still existed) and whether these records were maintained. Post-war, the Volksbund also made their own records of transferrals and finds, etc with ,usually, a set format of paperwork. Unfortunately, due to the size of the task, these records can be incomplete also.
German burial records can be, at best, described as "variable". Because of the period I'm interested in, I'm hoping I might be lucky here, however.
