Deletion of John Amson

Comment: Genus plant Amsonia was named after the subject of the article because he medically diagnosed then-Gen. George Washington with a cold, for which Washington feared was tuburculosis (or consumption). It is cited in multiple history, e.g. https://books.google.com/books?id=r3-rsrDiE5cC&pg=PT89&dq=%22John+Amson%22+williamsburg&hl=en&sa=X&ved=0ahUKEwi-m-zAj9rbAhUCIqwKHearCToQ6AEIOTAD#v=onepage&q=%22John%20Amson%22%20williamsburg&f=false ''Washington: A Life'' and floral books. I added the plant naming to the article. The subject's land holdings should be included as well. Easily passes
