alan was married three times. his first wife appears to have been a daughter of roger de lacy, constable of chester. it was likely upon this union that alan gained the english lordship of kippax as "maritagium" from his father-in-law. alan's second marriage, to david's daughter margaret, is dated to 1209 by the "chronicle of lanercost" and "chronicle of melrose". the date of alan's third marriage, to hugh's daughter rose, is generally thought to date to 1229, as stated by the "chronicle of lanercost". another possible date for this marriage is about a decade earlier. alan's second marriage, therefore, allied him to the scottish royal family, and his first and third marriages allied him to the two main branches of the powerful lacy family—firstly the pontefract branch, and afterwards the woebley branch.
