Drue de Monteacuto, upon the assessment of the aid for marrying the king's daughter, 12th Henry II (1167), certified his knight's fees to be nine in number, a half and a third part of the old feoffment and one of the new. He married Aliva, daughter of Alan Basset, baron of Wicombe, in co. Bucks, by whom he had issue, Drue, a son; an only daughter who became a nun at Shaftsbury; and William. After his death, she married 2nd, Richard, son of Gilbert Talbot, ancestor to the Earls of Shrewsbury.
His eldest son, also named Drue, who died during his father's lifetime, married, however, and left two sons, John and William. The elder son, John, was seated at March, in co. Bucks, a manor situated northwest from Alesbury and near the Oxford county line. He married Lucy, and had a daughter, Katherine, who married Warine Bassett. The younger son, William, had no male issue, but had two daughters, namely, Margaret, married to William de Echingham, and Isabel, married to Thomas de Audham.
He was succeeded by his younger son, William de Montacute. [Montagues in Great Britain, Terry and Jason Fritts, The Montague Millennium, Gladstone, Missouri]
