While researching my ancestor Robert Potter of Warwick RI, I ran across an article in PERSI by Myrna Hood which discusses the possible relationship between the Potter/Anthony/Paine families. Article was published in "Second Boat", Spring of 1996. More than likely, Robert Potter, Susanna wife of John Anthony, Nicholas Potter, and ? wife of Anthony Paine were siblings
Potter Profiles is a series of family newletters
put out by Donna Potter Phillips in the early 1990s and my brother gave me the CD version. Several issues have articles which discuss the probable relationship between the families. Maybe you can locate copies in a library.
