The “cross fourchetty” (French fourchette, “wishbone”) is a Continental charge, found in the arms of van Damme, c.1370 [Gelre 91]. Unlike the cross fourchy, it is not considered an artistic variant of the cross moline, but a separate form of cross.
Crispin MacCoy bears: Argent, a cross fourchetty and on a chief sable an eye argent irised azure.
