[citation needed] The surname Strickland (early forms include Stirkeland) is derived from the place-name Stercaland, given to a manor in the former county of Westmorland near Penrith, Cumbria.
[3] When Sir William de Stirkeland (1242–1305) married Elizabeth Deincourt (or d'Eyncourt),[4] Sizergh Castle became the seat of this Strickland gentry family.
A descendant, Thomas Strykeland is said to have carried the banner of St. George at the Battle of Agincourt in 1415.
They also gave their name to one of their properties, a settlement that first appeared on the west side of present-day Kendal with a motte-and-bailey fortification on it that became known as Kirkbie Strickland (Kirkbie is from Old Norse Kirkju, church, and by, village.[6]).
A Strickland gentry family seated at Gilsland was granted a coat of arms blazoned: Sable, three escallops argent, meaning "three white scallops on a black field".
