Hello, I believe that William Boundy was a draper and Priscilla a school teacher/ assistant at Lelant School. I found Priscilla's grave today. I co-ordinate the Lelant Heritage Centre. Here is the inscription on the head stone.
In loving memory of Priscilla, beloved wife of William Boundy who died July 19th, 1889, age 54 years 'Blessed are the dead which die in the Lord'.
