Please, I need more info on Frederick William Harrison, presumably born in Caswell County, NC, graduated from UNC, third in class in 1825; received M.A. in 1832 and then M.D. Said to have practiced medicine in Eastville, VA, but when and where else? Is listed in 1850 and 1860 Brunswick County, VA censuses and slave schedules as Frederick William, Fed W. and/or F. W.

Dr. F. W. Harrison and Dr. W. W. Wilkins attended the Drumgoole-Dugger Duel in Lawrenceville, VA in 1837.

Can find no evidence of his up-line nor of his descendancy. Have no record of his marrying. The 1860 census shows Martha P. Harrison a sister, in the home. This Martha P. Harrison was living in the home of James P. Harrison next door to F. W. in the 1850 Brunswick Co., VA census.
He is also found in the "Virginia Slave Births 1853-1865".

Have a copy of his will but no other stories and no other records.
He is my Brick Wall, Please help!
