G pett + ?
While no etymology suggests itself for the second element rachn-/rochne-, it is worth considering the possibility that it originally began with f which was lenited (and thus lost) in the Gaelic-speaking period. This might then suggest G fraoch ‘heather’, with some kind of n-extension terminating in the common locational suffix –in ‘place of, place at’, which would have become -ie/-y long before the earliest form of this name is recorded in the early seventeenth century. While the diphthong in G fraoch (OIr fráech) has developed as /Ã/ or /¬/ (as in Freuchie FAL), there is an OIr singulative form froíchne ‘sprig of heather’ (DIL), which may account for the different development of the vowel in Pitrachnie.
Compare also the specific in the lost place-name Drumreichnak, Drumreiknauch, etc., probably in AMY (discussed under *Drumreichnach AMY, PNF 4). There is also Dalrachney by Carrbridge, Duthil and Rothiemurchus INV.
