Are there any Duff's out there (straight male descendants with the last name of Duff) that have descended from Adam Duff of Clunybeg? I haven't found any yet. It seems from history this branch has been hard of luck in producing males. My 4th Great Grandfather (Alexander Duff) who came over from Scotland to Canada only has a handful of male Duff's left, and all in Ohio.
Thanks!
Rick Duff
