So what you are saying, Paul, is that somewhere you have seen a definition of 
"shillard" that matches "Steelyard"? And/or other scholars have analyzed the 
term and come to the same conclusion? I am sure most folks would find that 
strong evidence. However, I recall an instance in which someone here in 
California mis-translated "casamata" at the Royal Presidio de San Diego to mean 
"butcher shop/butchering house," only to find that the association with the Spanish 
Army fort meant, in this case, "casemate" or powder and ball storage building. 
It is for this reason that I am cautious with jumping to conclusions.
