Pardon me, but surely Frisian (the language) _does_ extend into modern
Germany - it lies mostly along the region from Denmark - Germany -
Netherlands.  Specifically, on the mainland East Frisian is found in
Oldenburg (east of Kiel), North Frisian overlaps the Denmark-Germany border,
and West Frisian is found entirely within Germany, (although also on the
islands along that remarkable coast, some of which are claimed by the
Netherlands).
