Over the last few years the Dundas Rootsweb forum has generated much discussion about the many branches of the Dundas name and how they might be connected. Although many people have done a huge amount of research on our Dundas roots much could be learned if DNA matches were identified which could link the different branches.

Current researchers are spread across the globe in Australia, New Zealand,
Canada, US, Surinam, Norway, South Africa, Ireland, Wales, England and
Scotland. Some of the cadet branches and septs now being verified are:

Dundas of Dundas
Arniston
Fingask
Zetland
Manour
Duddingston
Melville
Clobemon Hall
Beechwood
Fermanagh
Newliston
Magdalens
