Are you a mug if you get it wrong?

Some time ago the Cheshire Heraldry Society Programme Secretary approached me to ask if I could shed any light on the armorial bearings illustrated on a Chinese porcelain mug. Identified thus in David Sanctuary Howard’s book Chinese Armorial Porcelain:
1st Qtr identified as Kinsey
2nd Qtr attributed to Chardelow (of Spratling Norfolk)
3rd Qtr unknown
4th Qtr attributed to Grosvenor

This attribution is not correct.



I believe that the 2nd and third quarters are Birchels and the 4th quarter is Grosvenor (really Eaton).
I have expanded on this belief and given evidence to back it up in my talk entitled Squirrels and Chevrons.
