SH3384 : Llynon HallLlynnon or Llynon?Llynnon is the original spelling for the Hall; Llynon was a Victorian variant, now archaic. At various times Llynnon Bâch and Llynnon Mill, in the adjacent squares, have also been written as Llynon. The OS and the listed building citation use the archaic form for the Hall; Cyngor Sir Ynys Môn Anglesey County Council and the Royal Mail postcode database have reverted to the original.
The Hall's gatehouse has a stone plaque on its gatepost inscribed "Llynon Lodge"
SH3384 : Gateway to Llynon Lodge and Llynon Hall which has been retained as the preferred spelling by the property's current owners.
We may take it that the first element in the name is
llyn "lake" and the second
onnen "ash tree", hence "the lake where ashes grow" - there are no lakes in the vicinity today (just a couple of small, probably recent and artificial ponds) but there are plenty of wooded wetlands which in the past would have had seasonal lakes. That ashes were common hereabouts is evident from Llwyn Onn ("Ash Grove") the small wood in
SH3385 - but the stress in
llwyn falls on the second syllable (w) which rules out this being corrupted to Llyn(n)on.
