My reply #5 is carrying the wrong URL - I was trying to pick p this tome by John Guillim, 1679.

Thank you for this link which certainly demonstrates that there were books of heraldic templates indexed by name.
Did stonemasons creating monuments in the greater churches and cathedrals have access to such volumes? These were highly skilled, specialist craftsmen (not the sort of stonemason who could knock you up a lintel) creating expensive, luxury goods. It is likely that the master mason at least would have been literate. They may have followed a paper template - but who produced that?
My query is how were arms granted to a minor North Yorkshire family in 1616 exported to Suffolk in 1652 with no apparent, direct family connection?
