Mark’s paternal grandmother was Permelia/Pamela Goggin (the daughter of Stephen Goggin and Rachel Clark Moorman). Permelia was born in Virginia. Stephen was the son of Stephen Goggin, who was Irish, and of Lettice Boyd. Rachel was the daughter of Thomas Moorman and Rachel Clark.

Mark’s maternal grandfather was Benjamin Lampton (the son of William Lampton and Martha Patsy Schooler). Benjamin was born in Virginia. William was born in Durham, England, the son of William Lampton and Sarah. Martha was the daughter of John Schooler and Martha Wharton.

Mark’s maternal grandmother was Margaret Montgomery “Peggy” Casey (the daughter of William Casey and Erythusa “Jane” Montgomery). Margaret was born in Virginia or Kentucky. William had Irish and Welsh ancestry. Erythusa was the daughter of William Montgomery and Jane Patterson.
