gloria, i have never found a henry clark in my family nor have i known of a clark living in nebraska. my clark family came to the uas about the time of the american revolution and settled in nc. they later moved to ga, ala and tenn. after the civil war they dispersed from hardeman county, tenn to miss, texas ans ark. most went to texas. i am missing a lot of the families in the family, but not many are missing before 1880.
