We knew that Robert’s father was descended from Archibald, the 9th Earl of Argyll. Now volunteer Tom has just uncovered a compelling royal connection on Robert’s mother’s side, too: Robert’s mother, Sarah Buchanan, is a descendant of Robert II, King of Scotland. Here is a transcription of the family line, from Americans of Royal Descent: A Collection of Genealogies of American Families Whose Lineage is Traced to the Legitimate Issue of Kings (1891). We have bolded the sections that pertain to Robert and his distant grandfather, King Robert II. What a great find! Thanks, Tom!
