I am daughter of Wendell Acheson and Shirley Richardson Acheson. My father is son of Leslie Dryden Acheson and Christina Peterson Acheson. Leslie Dryden Acheson's parents are Robert Ramsay Acheson and Florida Catherine Childress Acheson. Robert Ramsay Acheson's parents are Robert Acheson and Eleanor McDonald Acheson. Robert Ramsay Acheson's parents may have been John Acheson and Sarah Ramsay Acheson. I have traced John Acheson and Sarah to Lancaster, PA between 1744 - ? From Lancaster they moved to Muskingum, Ohio and died in 1835 and 1853 respectively but these dates may be wrong. I lose the lineage before John Acheson who was in Lancaster, PA before the revolutionary war. Has anyone else followed this trail and could possibly give me a source for the parents of John Acheson - also if you know whether the family crest is the green and white or the red. Would love to hear from you.
