here from primary sources, starting with Roger le Breton who died
circa 1250.
From the Fine Rolls of Henry III (12 July 1223) we find an entry that
gives us a further generation back, viz to his father, Robert le
Breton, who died circa 1223:
"Derbyshire: Roger le Breton has made fine with the King by L10 for
his relief and for having seisin of a knight's fee with appurtenances
in Walton formerly of Robert le Breton his father, whose heir he is,
which falls to him by hereditary right, and the King has received his
homage and fealty."
This Breton family terminated in an heiress (Isabel) who married Sir
John Loudham (d 1387).
