Anthony, could you send me that link you speak of?
As you doubtless already know, the old baronial family of Allardyce had very close connections to the Arbuthnotts of Arbuthnott. For example, John Allardice of Allardice (d. 1500-1511) married Catherine, daughter of Robert, 10th of Arbuthnott. James Allardice of Kinneph (dc 1646) married Margery, d/o Robert Arbuthnott of Little Fiddes. See wwww.allerdice.net, the Allardice family website, and my monograph on the Allardice family.
