Jean Halyburton
Jean Halyburton, wife of Sir Henry Sinclair (c1345-aft 1400) cannot be the daughter of this Walter de Haliburton, who died about 1449. She had her last child in 1400 and therefore could not have been born much after 1355. Her father, if Walter, had to be born before 1340. There's no way the king was giving him appointments when he was 100 years old.
