It's known as Elfdalian on the English Wikipedia and on the
English-language _Linguist List_ Multitree.  There are almost 13,000
hits for "Elfdalian" in Google, presumably mostly English, including both
scholarly and popular sources.  In particular, the English-language page
at <http://elvdalsk.inss.ku.dk/om/english> about the Trið råðstemną
um övdalskų, also known as the Tredje konference om elvdalsk, at
Københavns Universitet calls it the Third Conference on Elfdalian.
