MoBio Jefferson, Alleged Sons and Microsatellites Chapter 3

It has long been suggested that President Thomas Jefferson may be the father of Eston Hemings, the last child of Jefferson's slave Sally Hemings. Members of Woodson family also claimed that they were the descendants of President Jefferson. The following shows the number of repeats in each of 11 microsatellites obtained from the Y chromosomes of their male-line descendants. President Jefferson had no surviving sons. Therefore, his uncle's descendants were used in this study (Foster et al. 1998. Nature, 396:27-28).

Descendants of President Jefferson's uncle:

15, 12, 4, 11, 3, 9, 11, 10, 15, 13, 7.

Descendants of Eston Hemings:

15, 12, 4, 11, 3, 9, 11, 10, 15, 13, 7.

Descendants of Thomas Woodson:

14, 12, 5, 11, 3, 10, 11, 13, 13, 13, 7.

This result indicates that Eston Hemings and Jefferson are genetically related, but Thomas Woodson's father was not a Jefferson. For further information on this controversy, please consult Report by Thomas Jefferson Memorial Foundation (January, 2000).
