While doing genealogical research on my wife's colonial Throckmorton ancestry I came across this article: Moriarty, G. Andrews, The East Anglian Blennerhassets, New England Historical and Genealogical Register 98:271, 1944. He reports a large family in Frense, Norfolk and believes there is a connection to the Blennerhasset family and village in Cumberland, where an Alan de Blennerhasset was a testatee of several wills, an Alan Blennerhasset was mayor of Carlisle in 1382 and a John Blennerhasset M.P for Carlisle in 1381 and 1384.
