Agatha de Vaux, Heir of Dirleton

It seems pretty certain that the first Vaux of Barnbarroch was a cadet of the house of De Vaux of Dirleton. The following extracts from the Official Guide book to Dirleton Castle summarise what is known of that family:-

During the reign of David II (1329-1371), a daughter of this last-named baron married John Halyburton, the second son of Sir Adam Halyburton of Halyburton.

Married

1. in 1340 / 1355 to John Haliburton died in August 1355 at Battle of Nisbet. Children include
2. Sir John Haliburton+1 d. a 1402. Married Margaret Cameron.

It is thought that the statement in the above that William’s daughter inherited Dirleton is inaccurate. It was his granddaughter, she being the daughter of his eldest son who predeceased him. William, the last baron de Vaux seems to have died in 1392 and he was married to a Catherine Douglas. As his granddaughter was married in or prior to 1355, it is unlikely that any of his younger sons would have been born later than about 1350 so there as a gap of at least 100 years to fill between that date and the Barnbarroch Charter of 1451 (1)
