THE TOWNLEY CLAIMANTS
...
... The estates cover 40 000 acres of land in England. They are known as the Townley estates, in the counties of York and Lancashire, and the Vane Tempest Estates, comprising extensive mining properties at Stella, Blaydon, Ryton, Winlaton, and Stanley in the County of York, Lancashire, and Durham. They are now in the hands of the Imperial Government and managed by the Marquis of Londonderry. Elizabeth Townley, of Lancashire, England, married Sir Robert Lawrence in 1504, and she was willed 30,000,000 dols., which was never paid over. Mary Townley married John Lawrence in 1693. The Vane Tempest estate came to the Townley family through the marriage of Sir Richard Townley to the heiress of Lord William Widdrington in 1665. ...
According to the newspaper, apparently an Act of Parliament was passed on August 4th, to deal with the claims.
1883 Book
In 1883 James Usher published a book
History of the Lawrence - Townley, And Chase - Townley Estates in England.
There is a copy on Open Library which directs you to archive.org but seems to deal with the Lancashire Townley Pedigree and their links.
Seems to be nothing for Whitehaven or Stanley on the quick search. But a reference to Cumberland and Durham.

But they have
... estates known as Townley Hall, Howard Estate, and Widdrington Estate, and found over thirty thousand acres of improved lands, and city and village property, therefore yielding all a large revenue. That the three estates above named are lying in the Counties of Cumberland, Durham and Lancashire.
The 107 page book is far too brief to deal with the acreages mentioned.
If the Act of Parliament has a full Survey of the all lands, you should get a lot more detail and usually names of individuals occupying the properties, farms, lands and places (the Tenantry, when Surveyed).
ADDED:
There are quite a few references to "Townley Hall" on Rootschat?
But whether you can discover the Manx naming connection and why, I leave that up to you.
