I was researching another family from the old Westmorland County (now Cumbria) and found this old newsletter.

It contains research on two principle families carrying the Strickland name. These are the Stricklands of Sizergh Caslte in Westmorland. Of additional note, one of these Stricklands was the navigator for the early explorer Sebastian Cabot.
Also contains lineage of Elizabeth d'Eyncourt and some information on Walter de Vaux.
