children: Sarah, did not survive to adulthood. Elizabeth, born February 24, 1752; married Francis Eppes, the first cousin or nephew of John Wayles first wife, Martha Epps Wayles. Elizabeth and Francis Epps had two sons, Richard and John Wayles Eppes, the latter of whom married Thomas Jefferson's second daughter, Mary Jefferson. Tabitha, born November 16, 1753; and Anne, born August 26, 1756, married Henry Skipwith (born 1751). Wayles' second wife died sometime between August 1756 and January 1760. On January 26, 1760, Wayles married his third wife, Elizabeth Lomax Skelton (she was the widow of Reuben Skelton, an older brother of Bathurst Skelton, his daughter Martha's first husband). The couple had no issue; she died on February 10, 1761. Betty Hemings and children As part of the wedding settlement between John Wayles and Martha Epps, her parents gave the new couple an enslaved African-American woman and her young mixed-race daughter Betty Hemings, whose father was an English sea captain named Hemings. After the death of his third wife, Wayles began a relationship with 26 year-old Betty Hemings. Betty already had four children: Mary, Martin, Betty Brown, and Nance. Wayles fathered six children on slave Betty Hemings. Children that were the offspring of slaves and the slave owner were sometimes called "a shadow family": Robert, James, Critta, Thenia, Peter, and Sally Hemings. As their mother was a slave, the children were all born into slavery under the principle of partus sequitur ventrum, which had been part of the law since 1662. They were three-quarters European in ancestry and half-siblings to Wayles' daughters by his wives. Wayles was not known to acknowledge his children by Betty, nor did he free her or them in his will. To do so would have communicated his relationship with Betty and would have required a change in Virginia manumission laws at that time. He did, though, allow certain freedoms for his children. For instance his two oldest children were taught to read and write, allowed to earn their own money, and allowed to travel by themselves. The youngest boy, Peter, was three years old when Wayles died. Hemings had two more children while she lived at Monticello named John and Lucy. Death and estate settlement John Wayles died at age 58 in 1773. He left substantial property, including many slaves, but the estate was encumbered with debt. Upon Wayles' death, Betty Hemings and her six children
