Hello Linda, My Henry Garretson was the father of Mary Garretson, b. Dec 23, 1780 and married to John Herdman (do marriage unknown) first child born 1800. Note on bible record that her father was a private in the Rev. War. This is all I know of Henry Garretson. Apparently there were a few Henry Garretsons as were there a few John Herdmans. I am trying to sort them out. I will keep your post and notify you when and if I find more information. Thank you for your post and best wishes for a Happy Holiday Season! Joy, Napa, CA
