I know it's a long time down the line, but if you go for http://heraldry.lordkyl.nethttp://heraldry.lordkyl.net, which is a cracking heraldry site, specifically in the public domain and downloadable, on (I think)page four of his gallery of blazonry is the Chal(whatever)coat used as a demo of heraldic terms. Sable, a chevron between three cherubim or. Page numbers at top of page. To see the exact Chaloner this was awarded to - I forget - google Burke's Peerage, and it shows up there in the alphabetical index. There are other coats, but this and very slight variations have been used by at least three branches who have been granted coats of arms, both in UK and Ireland.
