Born 1686.[4]

1710 Inheritance

Ninian Magruder, to receive "place that was my brother John Magruder's & 300 acres of upper part of Alexandria, plus share Lot #48 in Marlboro Town. [2]

1708 Marriage

Ninian is a boy, or should be, and these birthdates and fathers match, but I just realized that my (personal) notes list a different wife. Let's keep this unmerged until I can make sure I didn't pick the wrong profiles to merge. :)
