I don't know of a Henry (little horse) Lee. Robert E. Lee's genealogical line is as follows: Richard Lee d. 1664 m. Ann* Richard Lee (1647-1715) m. Letitia Corbin (1657-1706) Henry Lee (c.1691-1747) m. Mary Bland Henry Lee (1729-1787) m. Lucy Grymes Henry Lee "Light Horse Harry" (1756-1818) married twice: (1) Matilda Lee, of Stratford. Children: Lucy Grymes Lee (1786-1860) and Henry Lee (1787-1837), last "Master of Stratford."He died in Paris, France. (2) Ann Hill Carter, of Shirley. Children: Algernon Sidney (1795-1796); Charles Carter Lee (1798-1871); Anne Kinloch Lee (1800-1864); Sydney Smith Lee (1802-1869); Catherine Mildred (1811-1856); Robert Edward Lee (1807-1870) m. Mary Anne Custis. Seven children were born of this marriage, five of whom died unmarried.The two who married were William Henry Fitzhugh Lee (1837-1891) and Robert Edward Lee. I have no marriage of Henry Lee to Elizabeth Lee, as the line of Henry (Light Horse) Lee is as shown above.Again, I assume you mean "Light Horse" and not "little horse."
*Ann is believed to have been "Ann Farley", named for the ship "Ann", upon which her parents arrived at Jamestown, Va. in 1623.Whether she was born aboard the ship or shortly after her parents went ashore has not been proven.
