Newfoundland, New England, New York, Devon. Surnames: Dimond, Diamond, Dymond, Hall The Dimond of Newfoundland, New York / New England, Devon project evolved from the Dymond of Hudson River project, also at FTDNA. The Hudson River project was established to use Y-DNA technology with traditional research to confirm descendancy from Edward Dymen 1700, of Beekman and Rombout Patents, New York Province. Edward, his children, and grandchildren were found living along the Hudson River beginning in 1723. One well-documented son, Marcus, is then noted as being a settler of Stephentown as early as 1784. Marcus has been attributed in several published genealogies to being the progenitor of subsequent D*mond generations at Stephentown. Dimond of Hudson River Y-DNA testing suggested in 2003 that the Y-DNA signature of Edward Dymen belonged to haplogroup Q-M3, which denoted the indigenous peoples of the Americas. This result was confirmed through the testing of descendants of various branches originating with Edward, although Edward’s son Marcus was not represented. Then, in 2005 a descendant of the Stephentown Diamonds was revealed to belong to I-M253 (later tested downstream first to I-Z140 and then to I-A196), a North European haplogroup. In 2008 a second Stephentown descendant, as well as an individual who traced his ancestry back to the Greenbush / Sand Lake area, also tested into I‑M253. This left Marcus’s Y-DNA signature uncertain until 2013, when another participant confirmed that Marcus’s signature did indeed belong to haplogroup Q-M3. Subsequent research revealed the second D*mond lineage (I-M253) in Stephentown belonged to John Dimond c1755, who appears to have settled in Greenbush sometime during the Revolutionary War and whose sons and a grandson are later found in Sand Lake and Stephentown, respectively. Where John came from isn’t known, but there is an indication he was the John Dimond, resident of Boston, Massachusetts, who “reported a foreigner” for service in the Continental Army during the Revolutionary War. In 2011 a match arose between the Stephentown area I-M253 group and another Diamond participant, whose mariner ancestors had settled in Newfoundland around 1773. Although oral tradition suggested these Newfoundland Diamonds had originated in Devon, England, there was no paper trail to substantiate it. Further, additional research suggested it was also possible this family had migrated to Newfoundland just before the outbreak of the Revolutionary War and were associated with one of the mariner Diamond families (Kittery, Boston, Marblehead) of the New England coast. This, theory, too, has not been proved. In both cases, research is hampered (though not stopped) by the shortage of 18th century records. Nevertheless, an important link to Devon was established in early 2012, when yet another individual matched the I-M253 group. That individual, a Hall, traces his recent ancestry (i.e., as late as 1900) to Devon. Further, through subsequent testing, he was revealed to be a high resolution match (109/111 to the Newfoundland Diamonds and 108/111 to the New York / New England Diamonds), which suggests a fairly tight relationship. Given the different surnames (Hall/D*mond) and the close genetic distance, it is almost certain a non‑paternity event (surname change, undisclosed adoption, illegitimate birth) occurred, though when and on which side are currently unknown. Moving forward, the goal of this project is to synthesize the ancestry of these three groups and to determine the common ancestor. All individuals descending from one of these groups is welcome to join.
