On his 22nd birthday in 1880, Roosevelt married socialite Alice Hathaway Lee .   Their daughter, Alice Lee Roosevelt , was born on February 12, 1884. Two days after giving birth, Roosevelt's wife died due to an undiagnosed case of kidney failure (called Bright's disease at the time), which had been masked by the pregnancy. In his diary, Roosevelt wrote a large 'X' on the page and then, "The light has gone out of my life." His mother, Mittie, had died of typhoid fever eleven hours earlier at 3:00 ., in the same house. Distraught, Roosevelt left baby Alice in the care of his sister Bamie in New York City while he grieved. He assumed custody of his daughter when she was three.
