Ancestors of Ann Walter Fagerroos

I am searching descendants of James Harris, born abt 1740, (wife Mary ANN Mckinney),first confirmed in Rockbridge,VA,Green/Barren, KY and later family in Preble, OH, IL, IN, IA, etc.
Also, Robert Withrow (wife Jennet) of PA abt 1700, descendants moved various states, mine to Hancock, IL, Montgomery,IA.

Also, Henry Worst,(wife Barbary Donat)Berks, Pa. to Ashland/Wayne, OH 1814. son Jacob married Susan Martin abt 1833.
Henry had 10 children most of whom remained in the same area.
