Dear Dave, I would like to enter the DNA study on behalf of my husband's family. My husband is willing to participate plus I have four sons who would be willing to participate. (Too bad I can't loan one of the sons for the study). I have found it very frustrating that I can trace these Strongs back to 28 year old Clifton L Strong in the 1850 census in Campbell County, Virginia but have been unable to connect these Strongs to other Virginia Strongs. Clifton L Strong -- b 1822 or 1821 in Virginia Oden Clay Strong -- b 1845 in Virginia d 1891 Robert Fleming Strong -- b 1888 in Virginia d 1953 Robert Fleming Strong (changed name to Woodrow Fleming Strong) -- b 1910 in Virginia d 1983 Robert M. Strong -- b 1930 in Maryland Please let me know how to proceed. Thank you, Sharon Lafferty Strong
