I know very little about family crests but I have reached a dead end tracking down the maker of this Hanoverian tablespoon.


The mark is quite rubbed, but through a little twisting and turning I believe the letters are C (or, possibly, G), A, perhaps a space, S (probably), A, R (or P or B) and D (or D ligature or D with stroke).
Best guess is CASARD, but other possibilities abound.
Google tells me that the last letter, if not an ordinary D, could be DE or pronounced ETH.
I have searched American names for the 1740-1780 or so time frame and explored Aberdeen (mainly Coline Allen), but nothing with a distinctive "D" pops up in Richard Turner's fine work.
I would be grateful for any help to at least point me toward the right country.
Thank you.
