Some 25/30 years ago I purchased from the J.L. Hudson Department Store's art/book department 3 pages from a book of heraldry. The pages are 10" x 18", printed on one side of heavy stock paper. Page 410 is the title page and displays a large coat of arms. Under the coat of arms is written "The Right Honourable Robert Hampden, Baron Trevor". Page 411 is a double spread "A Genealogical Table of the Noble Family of Robert Lord Trevor, Baron of Bromham".
The last generation on this table includes " John Trevor, 3rd son. of Travallyn, Placetage,& Glynde, App. Lord of the Admiralty 1742, dyed.1745. S.P." married "Elizabeth, dau. of Sir Thomas Frankland, of Thirtleby, Bar. died 1744."
