The son of Sir
Walter fitz Gilbert of Cadzow de Hameldone, he succeeded his father as Baron of
Cadzow before 1346, when he was captured at the
Battle of Neville's Cross. He was considered an important enough captive to be held by
William Zouche,
Archbishop of York, under special terms that he not be released, except under command of
Edward III of England. He is thought to have been knighted prior to the battle. The next reference to David fitz Walter is in 1361 when he endowed
Glasgow Cathedral with a Chaplainry. In 1368, he received confirmation from the King,
David II, of his patrimonial Lands of Cadzow and elsewhere, with the addition of the lands and tenantry of
Eddlewood. David fitz Walter took part in the sittings of the
Parliament of Scotland in 1371 and 1373, the latter to confirm
John Stewart, Earl of Carrick and his successors as heirs to the throne of Scotland. The charter, at
New Register House in
Edinburgh, still has his seal appended, with the three
cinquefoils for Hamilton, and the inscription,:
Sigill David filii Walter. ==Marriage and issue==
