[Benjamin West, Jr.][1] was the son of Benjamin West, the artist.

"Perthall" is likely a misreading of "Pershall," an estate and family in Staffordshire that is well-documented. The misreading is due to the 1700s-early 1800s use of the "long s" which can be mistaken for an "f" or a "t":

The misspelling "Perthall" also appears in Robert C. Alberts' [_Biography of Benjamin West_](https://archive.org/details/benjaminwestbiog00albe_0/page/306/mode/2up?q=perthall).

The "[England, Staffordshire, Church Records, 1538-1944][4]" database shows that Mary Dickinson of **Eccleshall, Stafford** obtained a license to marry Benjamin West at Atcham, Shropshire.

The [Pershall estate](https://goo.gl/maps/WFRdQ7xvgVJs4b2s8) is about 1 mile outside the town of Eccleshall. [Some](https://historicengland.org.uk/listing/the-list/list-entry/1374232) of the [Pershall buildings][5] are [listed][6] in the National Heritage List for England.

The wedding was noted in the [Monthly Register and Encyclopedian Magazine  1803-09-01: Vol 3 Iss 17](https://archive.org/details/sim_monthly-register-and-encyclopedian-magazine_1803-09-01_3_17/page/276/mode/2up?q=pershall):
