Although William de Douglas was the first known owner of Douglasdale, holding that land between 1174 and 1213, there is no reason to doubt that his father was “Theobaldo Flamatico” or Theobald the Fleming. The family’s arms indicate the kinship with Murray and a descent like that of Brodie and Innes, from a third son of the house of Boulogne. In Flanders there was a family of the Theobalds who were hereditary castellans of Ypres between about 1060 and 1127, after which their history becomes obscure. Theobald’s lands in Scotland were granted to him soon after 1150 by the Abbot of Kelso. William de Douglas, the heir, having married the sister of Friskin de Kerdale or Freskin of Moray, had by her six sons; the five younger of them all went to Moray to support their uncle there and his own heir, Archenbald, stayed in Lanarkshire to inherit the Douglas estates. Archenbald married a daughter of Sir John Crawford.
