Note B — Part II.
Reading edition
The Lady Mary Percy was niece to Francis and Mary Slingsby (daughter of Sir Thomas Percy), of Scriven Hall, whose monuments are still to be seen in the Knaresbrough Parish Church. Dr. Collins tells me that “Sirsbie” was then “a Knaresbrough name,” and occurs in the Knaresbrough Parish Church Registers of that period. The name “Sizey,” which is given in Peacock’s “List,” under “Knaresbrough,” is probably the way “Sirsbie” was pronounced, just as “subtle” is pronounced “su(b)tle.”
