About Baldwin de Boulers
Lived 1075 – 1112 (aged 36–37). Baldwin de Boulers was a feudatory.
Baldwin de Boulers came to England in 1105 when he was granted the Lordship of Montgomery, Powys in marriage with Sybil de Falaise. Sybil was referred to as the niece of Henry I of England but is commonly believed, probably incorrectly, to be one of his illegitimate children.
Baldwin was of a Flemish family from Boelare and his father was Stephen, Baron de Boelare. Boelare is now known as NederBoelare and is part of the town of Geraardsbergen, East Flanders, Belgium.
The de Boulers were based at Hen Domen, the original site for Montgomery Castle and it is from Baldwin that Montgomery gets its Welsh name, Trefaldwyn "The Town of Baldwin".
The de Boulers continued as a prominent Shropshire family, becoming the Bowdlers.
