Dear Joseph: I cannot tell whether I could help you or not, as the only information you gave about the person about which you were inquiring was the name of a Hundred. It would make it much easier to identify a person with such a common name if you furnished dates -- even approximate ones, and any other information that you might have. My wife has Kellum ancestry from Somerset County, MD, in the 17th and 18th C., including some John Kellums. However, since I have no idea where Bogerternorton Hundred is or was, I have no possible way to know whether or not my information would be of any use to you. Allan E. Green
