This is a Message Board Post that is gatewayed to this mailing list. Surnames: sweet swett sweat switt swete Classification: Query Message Board URL: http://boards.ancestry.com/mbexec/msg/rw/HBRBAIB/1354 Message Board Post: It has long been the accepted view that these three surnames (Sweet, Swett, and Sweat) and several other similar ones are all variants of each other and might all share a common ancestor. While that may be true in theory, we now have results from DNA testing that show it to be incorrect in the cases tested so far. There are 20 test subjects with the family name SWEET, 5 with SWETT, and one with SWEAT. Nobody with one name matches anybody with a different name. (Not yet, anyway.) Where there is no match, there is no close relationship either. For more details, see our web page http://www.fairleafarm.harvard.ma.us/dnasweet.htm John Chandler
