Lamar's first wife, Tabitha Jordan, died in 1830, followed by his son, John Burwell, in 1831, and his daughter, Rebecca Ann, in 1843. His second wife, Henrietta (1827-1891), was the daughter of John Newland Maffitt, Sr., a renowned Methodist minister, and Ann Carnic, who operated a popular boarding house in Galveston. Henrietta and her sisters were celebrated for their charm and known throughout Texas as "The Three Graces." Henrietta and ex-President Lamar married in 1851 after a brief courtship that began during a chance meeting while visiting a mutual acquaintance in New Orleans. She was active in Richmond society, a devout member of Calvary Episcopal Church, and long remembered for her charity to Confederate soldiers and their families during the Civil War. She was entertained at the White House by First Lady Harriet Lane, niece of the bachelor James Buchanan, and dined with Jefferson Davis, president of the Confederacy. After Lamar's death, she continued to manage the plantation and increased cattle production, with up to 200 head bearing her letter H brand. She later moved to Galveston with her daughter, died in Santa Anna, Texas, in 1891, and was buried in Morton Cemetery in Richmond.
