Conrad and Katherine were VERY common names in village Huck but Bohl was certainly a surname in the village. I am the Huck village coordinator for AHSGR and have Bohl records from the original settlers to 1858. There are no known records for Huck in Russia for the period of 1858-1888. If you will tell me what you believe was their approximate birth dates and also when they were married I may be able to assist your research. If birth and marriage occurred during that dark period I have little to offer. Consider using my direct e-mail firstname.lastname@example.org
for future correspondence about this matter.
