Although historical sources attest to a variety of spellings (such as Moel Famma, Moel Vamma and Moel Fammau),[REF] the only two in common use today are Moel Famau and Moel Fama.
The alternative form 'Moel Famau' is a result of an 'antiquarian perception' first attested in the eighteenth century that the second element was the lenited form of the common noun mamau ('mothers') [REF].
