Alfred B. Hilton
Medal of Honor Recipient
Alfred R. Hilton, Harford County's sole Civil War Medal of Honor recipient and one of only 16 African American recipients for valor during the war, was born about 1837 and reared here on his father's farm in the free black community of Gravel Hill. He was one of manumitted slaves Isaac and Harriet Hilton's 14 children. Like Havre de Grace, Berkley and Kalmia, Gravel Hill was a post on the Underground Railroad before 1864. In 1860, the county's 3,664 free blacks were double the number of slaves and constituted 16 percent of the total population.
