As settlers of the Martha's Vineyard communities of Tisbury and Chilmark in Massachusetts migrated from the Kentish Weald, Nora Groce (1985) speculates that OKSL may be the origin of Martha's Vineyard Sign Language, which is, in turn, one of the precursors of American Sign Language (ASL).[3][page needed] Others have cautioned against uncritical reception of this claim, "because no deaf people were part of the original migration from Kent, and nothing is known about any specific variety of signing used in Kent."[4]
