Notes for Joan Montgomery
The following was recorded from a tombstone in 1609:
"Hic jacet Thomas Boyde, Dominus de Kilmarnock, qui obiit septimo die mensis July 1432, et Johanna de Montgomery eius spousa. Ora pro iis."
It is not know whom her parents were and the ones suggested, though with no evidence, would make her grand-daughter Margaret marry her half-uncle.
