I was right about Thurnham. See "A History of the County of Lancaster" Victoria County History series volume 8 pages 101-105. Available to read as BHO British History Online.

Thurnham Manor
"Before the Conquest Thurnham
.. being held in 1066 by Earl Tostig. Afterwards it is found to belong to the Lancaster family
It thus descended to the Harringtons of Aldingham (fn
and through Bonvil to Grey, being held by Henry Grey, Duke of Suffolk, executed for treason 1554. The duke had in 1552 sold it to Thomas Lowrie, citizen of London (fn 9)

Footnotes:
7. Crown dues received by Thomas Parr of Kendal. (I didn't note date.)
8. Elizabeth Harrington married William Bonvil. Their granddaughter and heir, Cecily, married Thomas Grey, Marquis of Dorset. Their son, Thomas died 1530.
9. Sale to Thomas Lowrie included manor & lands, 2 water mills, 20 saltpits &c. in Thurnham, Glasson and Cockerham.
~~~~~~~~~~~~~
Katherine Parr, 6th & last wife to King Henry, was from Kendal.
Glasson has/had a dock on the River Lune. Lancaster was an important international port in 18thC.
Thomas Lowrie sold Thurnham Manor to Robert Dalton not long after and seemingly made a large profit . The Dalton family still owned it nearly 300 years later, in spite of having it confiscated twice, being on Royalist side in English Civil War and Jacobite in 1715. The Daltons were Catholic. A later footnote lists their holdings. Forton, home of my ancestors in 18thC, is on the list.
Edit. I don't know why an emoticon appeared after the name Aldingham in my third paragraph. Perhaps the Harrington family were the epitome of cool in their day. It should be the number 8. I can't get rid of it. 8 was there when I previewed it and also when I tried to amend it. Now I need the emoticon for puzzlement.
