Yorkshire Gazette 25th April 1835
On Tuesday, the 21st inst., at his residence in Fishergate, near this city, after a protracted illness of upwards of four years, in the 87th year of his age, John Prince Esq. He, along with his late partner, Mr. Hamson (sic), first established the extensive and most respectable business of goldsmiths and jewellers, which, for a long series of years, has been carried on in Coney Street. In the year 1793, he paid the usual fine for being excused serving the office of sheriff of this city. Although of late years his generosity to the poor - particularly at his own door - was not regulated by that discrimination which protected him from imposition, his extensive charities will, nevertheless, be long and gratefully remembered by the needy and distressed.
