According to the 1870 U.S. Federal Census, Martha Dean (c. 1813-1883) and Reuben Dean (c. 1812-?) lived in the Eastern District of Loudoun, Virginia. Enslaved by Reuben Settle, they had lived in a cabin with their six children, Caroline, Fannie, John, Charles, James, and Millie (Matilda), as listed on the 1860 U.S. Federal Census slave schedules. After Emancipation, Martha and Reuben remained in the cabin and worked for Thomas and Nelson Settle, sons of Reuben and Naomi Lyne Settle, and for their sister Susan. Their children Fannie and James also lived and worked with the Settles, and by 1870 Fannie was married to John Douglass. In his will, Nelson Settle bequeathed 142 acres including the cabin to Charles Dean, son of Martha Dean, as a reward for special services and for faithfully serving him and caring for his interests for a number of years, and Thomas Settle used similar terms in his own will. The acreage passed after the brothers' deaths in 1890. Dean descendants lived in the cabin until the late 1960's and remained in the Conklin community until the homes were sold to Toll Brothers for the extension of the South Riding community. Reuben Dean was also the uncle of educator Jean Serepta Dean, known as Miss Jennie, who established the Manassas Industrial School in 1894.
