Yes Norma, the Rollisons buried in the Monogahela Cemetery are descended from Jacob Rollison, my gg grandfather Isaac's brother. Maybe some of the other siblings who stayed there.My mother kept in contact with one of Jacob's grandsons up until his death in, I believe 1989. They are the siblings of your Benjamin. I was in contact with this branch of the family, until recently. As a child, my mother went to Monogahela with her family to square dance.Both Isaac and Jacob called the dances.
