The family takes its name from the village of Blennerhasset (thus spelt now), Cumbria (formerly Cumberland), N England.
The family took their name from this place but they did not have lands there (or at least, not since the 12th century).
Their main lands were at Carlisle, Cumberland.

We start with:

Richard de Blennerhassett,
of Carlisle, Cumberland,
mar Joan Skelton [dau of Sir Clement Skelton by his wife Joan de Orton, dau of Sir Gyles de Orton, of Great Orton],
she was co-heiress of Great Orton, just W of Carlisle (see map),
she died 1450,
had issue:

John de Blennerhassett,
of Great Orton, Cumberland,
Mayor of Carlisle, various dates 1430-55.

Ancestor of:

John Blennerhassett,
of Flimby Hall, Flimby, Cumberland,
Manor of Flimby purchased 1547,
died 1578,
had issue:

  1. Thomas Blennerhassett,
    of Flimby Hall, Flimby, Cumberland.
    He claimed in 1578 the advowson of the Rectory of Great Orton as co-heir of Sir Gyles de Orton.
    He was granted lands in Ireland in 1590.
    Ancestor of Blennerhassett of Co.Kerry.
    Almost all male line Blennerhassetts in the world today seem to descend from the Irish branch.
    The Cumberland male line seems extinct.
