William Danielstoun or Dennestoun was keeper of Linlithgow Palace for James V of Scotland. Danielstoun was made keeper of Linlithgow Palace on 19 November 1540, replacing Thomas Johnston. His annual fee was £50 Scots. He was a Bailie of Linlithgow and Sheriff-depute of Linlithgowshire. He found some gold coins in Linlithgow in 1540. James V granted him lands in Linlithgow on 6 December 1542, presumably rewarding him for his work at the palace for his wife. This was one of the last grants made by the king before his death. He had a son, James.
