The Clephane family was prominent among elites in Washington, D.C. James O. Clephane's brother —
Lewis Clephane—was named Postmaster of District by Abraham Lincoln, tapped for a senior role at the
United States Department of the Treasury by Salmon P. Chase, and occupied an influential role in Washington's high political society. James O. Clephane and Lewis maintained close relations with President Lincoln and his family. Lewis Clephane is also credited with founding the Republican Party and early abolitionist efforts amid majority pro-slavery elites in Washington. Further, Lewis Clephane went on to be the publisher of pro-Lincoln newspaper, The
National Republican (newspaper). He would eventually build a mansion at the corner of 13th Street Northwest and
K Street (Washington, D.C.) Northwest. The Clephane family can be traced back to the family's noble roots, with their initial settlement in what is now
Scotland directly after the
Norman Conquest. Between 1200 and the
Battle of Bannockburn, the Clephanes acquired lands of
Castle of Carslogie, which became their primary seat. They constructed the castle in 1590, and the ruins of the castle still bear the date's inscription. The castle was handed through generations until 1804, when Major General William McLean Douglas Clephane sold the castle and barony lands prior to dying. Lewis Clephane would remain in Washington, D.C., as a key figure in the city's upper echelon, and becoming a co-founder of
Metropolitan Club of Washington, D.C. His son, Walter Clephane, would remain prominent and lived in
Chevy Chase (Washington, D.C.). In the late 19th century, James Ogilvie Clephane relocated to the
New York metropolitan area, seeing great success in his financier work following the successful inventions from years prior and directorships in subsequent mechanical printing companies, such as
Mergenthaler Linotype Company of New York, New Jersey, West Virginia, and other iterations that had paid its stockholders and founders dividends over a three-year period of over
US$119,000,000 (in 2023 dollars). His family moved to an estate in Englewood, New Jersey and are consistently listed in the
Social Register throughout the 19th and 20th century, as was Lewis Clephane's family in Washington, D.C. ==Other==
