My Great-grandfather John Mather Pryce and his mother Elizabeth came from Shrewsbury. His birth is registered as John Mathew PRYCE Q1 (Jan/Feb/Mar) 1840 Shrewsbury GRO Ref XVIII (18) 178. By 1861 he has moved to Birmingham but I would love some background on his parents if any exists. Later the family changed their name to PRICE not sure why. :D
Have you spoken with any of the local (Shrewsbury) Pryces? At least until very recently, one Alan Pryce owned and managed a camera and film shop near St. Mary's Church (Photo-focus, 20 St. Mary's St.) not far from the Yorkshire House. I believe that this Alsn Pryce is the Alan Pryce whom I knew back in the 1967-73 era, when I was in Shrewsbury doing historical research. In 1967 the Alan Pryce I knew (and his parents) lived just outside Shrewsbury, and thus would be a local with some local roots. If all this is so, he might guide you and your search.
If you do meet or speak with Mr. Pryce, and he recollects going into the Yorkshire House at that time, tell him I'd like to get in touch. My email is vjwesq@comcast.net, and I'm in Valley Forge (Pennsylvania).
