Thomas H. Osbourn was born in Maryland in 1820 and died in 1883.
As a youth he attended the Alexandria Boarding School in Alexandria, Virginia. In 1853 he was elected sheriff in Prince George's County and was a member of the Whig party. Osbourn was a tobacco farmer in Prince George's County, Maryland, for many years. He owned property south of Upper Marlboro, Maryland, near Croom, and also south of Brandywine, near the Baltimore and Potomac Railroad line. The tax records of his heirs indicate property names of Pt. Timberleigh and Linwood. He and his wife, Eliza Ann (1824-1902?), had at least twelve children. Three daughters, Eugenia, M. Louise, and Anna died within a few days of each other in November 1861. Another daughter, Mary (1846-1922), married John Wallace (1856-1896). Their daughter Edith (1884-1977) married Murray Metz. Eliza Ann, Thomas's wife, inherited his Prince George's properties at his death. Following her death about 1902, their daughter, Mary, and grand-daughter, Edith, inherited the remaining properties.
