undistinguished families--second families, perhaps I should say. My mother, who
died in my tenth year, was of a family of the name of Hanks, some of whom now
reside in Adams, and others in Macon countries, Illinois. My paternal

Indians, not in battle, but by stealth, when he was laboring to open a farm in
the forest, tits ancestors, who were Quakers, went to Virginia from Berks

names in both families, such as Enoch, Levi, Mordecei , Solomon, Abraham, and
the like.
My father, at the death of his father,
