I consider, in the name of "Taphorn" derived from the Low German. The High German word "tap" is in Low German "Tapphoan," which a close phonetic relationship would be given at least. Given the regional distribution of the name Taphorn (see, for example be verwandt.de) also lies close to a derivation from the Low German.
