Remarks:
Name Suffix: Of Bideford, Sir
The name of Bidford is a corruption of itsoriginal appellation, By-the-ford. The manor was settled by William the Conqueror on his consort Matilda, and was given by William Rufus to Sir Richard de Grenville, whose descendants resided her and at Kilkhampton, in Cornwall, for many generations; and three of them represented Devon in Parliament. [Brad Verity, citing White's Devonshire Directory of 1850]]

Louise Staley, in her post to SGM, citing "A History of the Granville Family, etc.", has Richard as brother of Robert Fitz Hamon and son of Hamon (Dentatus), while I have Richard as brother of Robert Fitz Hamon and son of Hamon (Dapifer). The brother is the same, but maybe her source missed a generation (Dapifer).
