Their only child was Maria Barbara Baynton (b. ca 1780). She became her father's and grandfather's sole legitimate heiress as declared in the entail of 1788. Sir Andrew Bayntun-Rolt, 2nd Bt., remarried, but had no male issue apparently. The second page implies that Maria Barbara was his eldest daughter, and perhaps his only living child or his eldest living daughter in 1788. She in turn eloped in 1797 aged 17, and married a mere reverend; however, she inherited her father's estate in 1816. Her son John Edward Andrew Bayntun Starky (1799–1843) inherited the estate, which was sold in 1864 to pay the debts of his son John Bayntun Starky (1834–1872) - while his grandmother, the second heiress, was still alive.
