Margaret Tudor
The castle played host to the royalty of Scotland. James IV wooed Margaret Drummond at Cumbernauld Castle, where Margaret's sister was married to Lord Fleming. The Drummonds' sisters lie buried in Dunblane Cathedral following their poisoning by a government determined to marry an unwilling King James to the sister of Henry VIII of England, Margaret Tudor. The murders made James IV a frequent visitor to Cumbernauld, Margaret Tudor accompanying him on one occasion.
