Hogdal
Hogdal is a name for the valley around the Hoan River. In the historical province of Hälsingland, Ytterhogdal lies downstream from neighbouring Överhogdal. The older district name appears in a copy of a 1273 document; the two parish names later distinguished the lower and upper parts of the valley.
Ytterhogdal was a separate parish by 1402 and part of Ljusdal's pastorate until 1562. The old frontier ran between Ytterhogdal and Överhogdal: the latter lay in Härjedalen, which passed from Denmark-Norway to Sweden in the Treaty of Brömsebro in 1645.
