GENEALOGY:

Henry Beekman Livingston was born November 9th, 1750 at Clermont to Judge Robert R. Livingston and Margaret Beekman. He was brother of Chancellor Robert R. Livingston, Janet Livingston (widow of Maj. Gen. Richard Montgomery), and Secretary of State Edward Livingston. He married March 14th, 1781 in Philadelphia Nancy Shippen (cousin to Benedict Arnold's wife—Arnold and Livingston were friends before the treason of 1780). Their only child Margaret "Peggy" Livingston was born December 26th, 1781 in Philadelphia. Peggy died unmarried leaving no one who (legitimately) descends from this Patriot.

He began his Revolutionary war career as a Captain, having raised a militia that drilled on the lawn of the Beekman Arms. He went as far as Montreal with his brother-in-law Richard Montgomery, but Montgomery sent him back to Albany after the city was taken. He felt great disdain for men in higher positions of power that he felt had lower social rank that he. He was a Colonel of the 4th New York Line at the Battle of Saratoga in 1777 and the Battle of Monmouth and the Battles of Rhode Island and Quaker Hill in 1778. Irritated that he wasn't getting promoted higher than colonel, he resigned his commission effective January 1779.

After this, he returned to Clermont and then to a house he inherited in Rhinebeck. Throughout his marriage to Nancy Shippen he was prone to extreme jealously and outrageous behavior that isolated him from his wife, child, siblings, and parents. Historian Geoff Benton summed up Henry Beekman Livingston perfectly when he said that "an ungoverable temper, surpassed only by a repugnant attitude, left him with an abbreviated military career, a spectacularly failed marriage and completely cut off from the rest of the Livingston's." You can read more about his dramatic personal life at clermontstatehistoricsite.blogspot.com. He died November 5th, 1831 "alone and unmourned."

I think you need to google this person. 1748 was birth year. Married twice. More.
