William Nelson Howard Stallings
A biographical sketch written in 1967 by grand-daughters Mary Stallings and Inez Stallings Brown states that the Stallings/Hussey family came in the Markham company. There is some internal evidence (Markham company rules found nowhere else) that leads credence to the authors' contention that the whole family came in the Markham company.
William's death date is confirmed by his obituary.
