I missed the earlier queries but I presume you are talking about Dunsmore in England. There are two well documented families, apparently unrelated, which came to the US from different areas in England. Richard Kellam came to the Eastern Shore of Virginia in the 1630s. It is my understanding that his line comes from the Kelham area near Nottinghamshir.The other group descends from an Austin Kelham who sailed fromYarmouth on the "Mary Ann" on May 11, 1637 and landed at Salem, MA. I understand his line comes from the St. James / Dennington, Suffolk area. Since you may be aware of these lines I will not get specific. If you are interested, there are many individuals who know a lot more than I about these surnames. I am sure they will respond with verified details if you indicate an interest. Ron Kellems
