My ancestors - Blennerhassett - Contents

Blennerhassett of Co.Kerry

I descend from the Cashel family, who descend from the Blennerhassett family of Ireland, though from what branch is not clear.

Blennerhasset village, Cumberland

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 lands were elsewhere around Cumberland.

Our line

The Irish Blennerhassetts all descend through the following line.

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 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.
