Haplogroup CTS3655 Overview

As with L627, there are a significant number of test-takers under CTS3655 which extend, downstream, to BY3368. However, the Z16539 and BY21628 subclades of CTS3655 indicate a different locale than what is seen in BY3368. Instead of their ancestors moving into the Lowlands of Scotland, test takers of the Z16539 stream are traceable to 18th and 19th century ancestry in East Scotland (Aberdeenshire, Inverness, etc) and, south, where it is believed CTS3655 is based in the Dumnonii of Cornwall, Devon, etc. Some of the English surnames of this line include Naramore, Hopking, and Coberley.
