Douglas Syphax (c. 1842 – 4 February 1890) or Douglass Syphax was an African American from Virginia who resettled in Philadelphia, Pennsylvania after the American Civil War. A military veteran, he was active in the Grand Army of the Republic in the late 19th century, and he also became a property developer in Philadelphia. 
He was one of the few African Americans to gain commissions as sergeants in the US Colored Troops serving in the American Civil War.
Background.
As a relative of Charles Syphax, Douglas Syphax was related to an African-American family in Virginia who were granted land in Arlington County, Virginia. In the 1940s it became part of Arlington National Cemetery.
The family was descended from Martha Washington (1731–1802), wife of President George Washington (1732–1799).
The family, considered part of the elite in African-American society, traces its origins to Mariah (with an "h") Custis, the mixed race daughter of planter George Washington Parke Custis (1781–1857), the only grandson of Martha Washington. Mariah's mother was Ariana Carter, one of Custis's house slaves.
When Mariah Custis asked her father for permission to marry Charles Syphax, one of his slaves, he freed them both, held a wedding for them in his Arlington mansion, and gave them fifteen acres of his Arlington estate. Mary Custis (1808–1873), Mariah's white half-sister, was to marry the Confederate General Robert E. Lee (1807–1870). 
Mariah and Charles had ten children, several of whom were given important political positions from the 1850s onward. Their eldest son, William Syphax, was eventually appointed superintendent of Washington's black segregated school district.
Life.
Douglas Syphax was born in Arlington, Alexandria, District of Columbia in about 1842. 
In 1864 he entered the Union Army, serving for ten months before being honorably discharged and reaching the rank of sergeant. He settled in Philadelphia, Pennsylvania, which had been a center of free blacks since the Revolutionary War. 
There Douglas Syphax married Abbie McKee, daughter of the wealthy African-American businessman John McKee, known by the honorific of Colonel. A free man of color, McKee had migrated to Philadelphia from Virginia in the 1840s. There he started work as a waiter, later becoming the owner of restaurants. He also moved into real estate and reputedly became a very wealthy man.
In the late 1800s Syphax also became involved in speculative real-estate, as Philadelphia industry was attracting many new residents. He hired African-American architect Calvin Brent to design houses for him.
He was a member of the Oliver P. Morton Post of the Grand Army of the Republic. Syphax was appointed to Post 3 in the Relief Committee of the Grand Army's Department of the Potomac, which was active from February 1888 to August 1889. It determined which Civil War veterans should be eligible for relief.
He died on 4 February 1890. His wife, Abbie, lived until 19 February 1923. Because of Syphax's military service, both were buried in Arlington National Cemetery.
Children.
When Colonel McKee died, he left Abbie Syphax a legacy of $300, and $50 for each of her children. Her nephew Henry McKee Minton, later to become a prominent physician, was also given $50. Most of the rest was bequeathed to the Catholic Church to fund a college for orphans. The will was disputed, and Abbie eventually gained $26,500 from Colonel McKee's will. When she remarried in 1904, she was reported to be "the richest colored woman in this city, and perhaps in the world."
Douglas and Abbie had five children.
