I to am a direct descendant of Archibald Wilkin, immigrant, thru his son Archibald II. I believe also that they originated in Scotland. My DNA results on ancestry.com show that I am 50% England & Northwestern Europe, 20% Scottish and 19% Irish. I'm not sure how to go about searching the Scottish connection with any accuracy. It is nice to know someone else is searching. Which one of Archibald I children is in your direct line? We are evidently related, just do not know how. Anyway, nice to meet you.
