Bookplate

I'm intrigued by the bookplate attached to a novel which arrived today, an 1845 reprint of Lady Morgan's Florence Macarthy (1818). It reads as follows:

Sir Samuel Wilson
Hughenden Manor
From the Earl of Beaconsfield's Library

(I'd post an image, but for some reason my camera is not cooperating.)

OK. Wilson (1832-95) rented Hughenden after Disraeli's death. How does one parse the bookplate? Did Wilson purchase the book from Disraeli's estate? Or does the bookplate simply mean that Wilson stored the book in D.'s library (literally)? D.'s title did not pass to his heir, Coningsby Disraeli, so the only Earl of Beaconsfield at issue here is D. himself.
