Looking for a Link...

You are presumably not looking at having a set of arms created, just looking for information. My dealing with the College of Arms was more years ago than I care to remember, but the cost then was just over £100. No doubt if you google you will find out what they charge now, but I would expect hundreds rather than thousands.

 

Halifax is actually better than Borthwick - it's the closest large town to where the Saltonstalls are said to have come from and a few of the American branch considered themselves "of Halifax".

Why does it not surprise me that something managed to get lost in translation?

Still doesn't fill me with inspiration to ask - I have to double anything that is in pounds to get something which approximates $AU and something that starts at $200 a long time ago probably might still be prohibitive and need some judicious saving first.

 

Update:
I can say (although this does not necessarily prove anything given the errors) that the Saltonstall arms appear in Papworth's Ordinary twice as follows:
1. Argent a bend between two eagles displayed sable - Saltonstall, co. York

and

2. Or a bend between two eagles displayed sable - Saltonstall, V*. Saltonston, co. York; and Lord Mayor of London 1597. Saltenstall London, granted by Cooke, V.

This would suggest that the arms were given to the Lord Mayor of London (I could be reading this incorrectly) in 1597, which means to Sir Richard.
