Alice has as her maritagium the manor of Kippax, Yorkshire.
The identity of Alan Fitz Roland's first wife is proven by a suit dated 1214 regarding Kippax, Yorkshire, in which Alan is stated to have married a sister of Richard (recte Roger), father of John (de Lacy), Constable of Chester. The year previously in 1213, an unnamed daughter of Alan died as a hostage in the custody of Robert FitzRoger of Warkworth, Northumberland. It was customary in this period to place foreign born hostages with a near relative in England. Robert FitzRoger in question was the maternal uncle of Alan of Galloway's first wife, and thus would have been closely related to Alan's child.
Alan and his first wife were possible married in 1200, when her brother, Roger De Lacy, was employed for safe conduct of the King of Scotland to the court of England. Omerod identified a sister Alice for Roger but doesn't provide her marital history. Quite possibley Alice was the 1st wife of Alan FitzRoland.
