Robert’s child­hood home, Augh­a­lane House in Coun­ty Tyrone, Ire­land. The blue plaque to the left of the door reads, “Most Noble Duke of Argyle” with a draw­ing of the Camp­bell coat of arms. The plaque on the right reads, “Hugh Camp­bell built this house in the year of our LORD 1786.” The “Hugh” referred to in the plaque is Robert’s father.

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!
