Here is a comprehensive, ongoing, list of all the presidents' brothers and sisters
Siblings of the U.S. Presidents
1st President George Washington (1789-1797)
b. February 22, 1732, d. December 14, 1799
Butler Washington(1716 – 1716)Butler Washington was the firstborn son of Augustine Washington and his first wife Jane Butler. He was the first of only three to die young in the Washington family. This was a remarkable feat considering the high mortality rate of infants and children during that era.
Lawrence Washington(1718 – July 26, 1752)Lawrence was sent to prestigious Appleby School in England shortly after his father’s second marriage. He served a naval commission to enter in war with Spain in 1740 under the direction of Admiral Vernon, in whose honor he would later name the family estate, Mount Vernon. Lawrence married the elegant Anne Fairfax shortly after his father’s death. The affection and respect between Lawrence and George Washington is well known. Since it was economically impossible for young George to go to the prestigious Appleby School after their father died, Lawrence mentored George Washington in how to be an exemplary gentleman, and he later opened doors for George into the society of Virginia’s most powerful men. Lawrence served in the House of Burgess, as Adjutant General of Virginia, and was in charge of his father’s iron furnace. He stepped down from his duties in 1748, due to consumption, and struggled from then on with the illness and his ability to serve. George Washington took his only trip outside the boundaries of what would become America when he accompanied Lawrence on a futile trip to Barbados, seeking to improve his health. He died soon after at the age of thirty-four.
Augustine Washington(1720 – May 1762)Called “Austin” affectionately by his family, he also went to Appleby School in England after his father’s second marriage.Austin proved to be a good student and dreamed of pursuing law but returned to Virginia at the insistence of his father, possibly for economic reasons. This put young Austin in poor spirits until the return of his older brother Lawrence from the conflict in Cartagena, Colombia. Austin married Anne Aylett and inherited one of the family properties after the death of his father. During the summer Austin would allow young George to stay with him for weeks at a time to send him to a surveyor’s school, and as a respite from George’s domineering mother.
Jane Washington (1722 – January 17, 1735) Nine years old at the time of her father’s remarriage, Jane received short-lived attention from her new stepmother, Mary Ball Washington, who became pregnant with George that same year. Considered the first sorrow of his life, George was three years old at the time of Jane’s death. She most likely died from influenza or pneumonia, as these were the leading causes of death at that time of year. Shortly after her death the family moved from Pope’s Creek to the property that would later be known as Mount Vernon.
Elizabeth (Betty) Washington Lewis, b. June 20, 1733, d. March 31, 1797. m. Fielding Lewis May 7, 1750 Had 11 children; only 6 lived to adulthood. Elizabeth, called Betty, was just sixteen when she married Fielding Lewis, her second cousin, three months after his first wife died in childbirth. It was a marriage based on family loyalties and deep respect.
Betty’s husband, Fielding Lewis, was an implacable patriot, and invaluable to George Washington. He was a wealthy merchant and ship owner, and much in demand for civic duties because of his even, careful mediation. He administered the first school for slave children in Fredericksburg, and was in business with George Washington attempting to drain the Great Dismal Swamp. At the beginning of the Revolution, Fielding Lewis was appointed director of Fredericksburg’s Gun Manufactory, and eventually impoverished himself to keep the gunnery open. Health worsened as he continued to push himself; finally he was too ill to continue. News of the victory at Yorktown reached the Lewis’s just before Fielding’s death of consumption in December 1781.
After Fielding Lewis died, Betty was left in financial straits, although she was a strict manager and was able to care for mother during her last stages of breast cancer, as well as for destitute nieces and granddaughters. Betty died of long-term respiratory illness.
Note about George Washington’s younger brothers:
One of the first acts of open sedition in the American colonies took place on February 27, 1766. In the fiery rhetoric of the time, patriot Richard Henry Lee wrote the Leedstown Resolves in Westmoreland County, Virginia, reminding King George that it was a “birthright privilege,” that no British subject could be taxed, “but by consent of a Parliament, in which he is represented by persons chosen by the people, and who themselves pay a part of the tax they impose on others.” One hundred fifteen men, including all of George Washington’s living brothers—and the father of future president James Monroe—promised that any “profligate” wretch who tried to impose this wicked Stamp Act would be “convinced” of the fact that “immediate danger and disgrace shall attend their prostitute purposes.”
Samuel Washington, b. Nov. 16, 1734, d. Dec. 9, 1781. (day undocumented) Three years after signing the Leedstown Resolves, Samuel was making final arrangements to move from Fredericksburg northwest to Frederick County, now Jefferson County, West Virginia. He had built his family a fine house he called “Harewood,” on land inherited from half-brother, Lawrence. He was appointed to county court that year, even though he had not yet moved his family. Harewood turned out to be extravagant expense. Married five times, Samuel struggled financially and looked to George to settle his debts, much to the President’s irritation.
Samuel also owned property where the hot springs town of Bath (also known as Berkeley Springs) was authorized in October 1776. He was appointed as a trustee, and was to lay out the streets of the new town. However, the Revolutionary War intervened, and the popular vacation spot would have to wait for its developer. Before that time would come, Samuel Washington would be dead. He died shortly after the American victory at Yorktown, and just a few days before his brother-in-law, Fielding Lewis. His sister, Betty, took in one of his orphans, Harriott Washington.
John Augustine “Jack” Washington, b. Jan. 13, 1736, d. Feb. 1787. m. Hannah Bushrod, 1756. Member of County Committee of Safety. Oversaw Mount Vernon while his elder brother was off creating a new country. As George Washington’s “most trusted brother,” Jack was his brother’s discreet sounding board. It was to Jack that George Washington would vent his frustrations over the war and a congress that couldn’t agree and couldn’t get them the tools necessary to fight the most powerful army in the world. Jack was the father of Supreme Court Justice Bushrod Washington.
Charles Washington, b. May 2, 1738, d. September 1799. Marries cousin Mildred Thornton, 1757, precipitating a family emergency, as he is only 19 and Mildred’s parents are worried about his financial status. George Washington gruffly writes that they obviously knew “little of the principles which govern my conduct.”
Charles was in a butchering business with George Weedon (later General in Revolution) for a time. He served as a Trustee of Fredericksburg and as a vestry member of St. George. During the Revolution, Charles was a member of the Fredericksburg Committee of Correspondence; he and his brothers collected goods for Boston and sent them on one of their brother-in-law’s ships, which successfully ran the barricade. Charles was also appointed keeper of the powder magazine, and as county escheator.
Charles took the land he inherited and built himself a town: Charles Town, West Virginia. He named the streets for family.
Mildred Washington (June 21, 1739 – October 23, 1740) When Mildred was born her seven-year-old brother George was just beginning to learn how to read and write. Mildred was named for either her grandmother or her paternal aunt, Mildred Washington-Lewis-Gregory-Willis. Mildred, the last of the Washington siblings, died in infancy just as her older half-brother Lawrence sailed to war in Cartagena.
