Hi Cousin. I am in the process of co-ordinating a Y-Chromosome Project. It involves Knowlton Males over age 18. Hopefully we will be able to get cousins in the US and GB to participate. We need to get at least 11 to participate to get group pricing. Oxford Ancestors in GB will do the testing and provide the test kits. Participants will receive their own chart from Oxford Ancestors and a group summary. If you think you might be interested and would like more info, please Email me back ASAP. My Great Grandfather is Stockings # 6916.
