I am currently a volunteer typist for "Tracing Your Roots in Greene County, NY" (http://www.rootsweb.com/~nygreen2). I've been wondering about this Greene County BRIGGS family for a long time.My Briggs family came out of RI to Hancock, Berkshire Co, MA ( I think they were Shakers or Quakers) There is a large Shaker Village Museum there now. Francis Briggs and Marberry Jones had a son Henry Briggs who eventually went to Otsego Co, NY and married Debbie Hopkins born in RI. They moved to Cohocton, Steuben Co, NY before 1820 and raised their family and died there, he in 1854 and she in 1856. Do you know where your first US ancestors located and if they connect back to John Briggs, 1609 RI.
