the name Kelling appears in place names in both Norfolk and in lower Schlesvig Holstein. It seems that it means cod fisher. In Norfolk there is a settlement on the coast called Kelling, while in Germany there is one called Kellinghusen. I have not yet been able to find out any history except that my Kelling forebears in Mecklenberg go back to the 1700s and I dont know what was before that. Wendy Kelling
