Llanfechain
Llanfechain is a small village and also neighborhood in Powys, Wales, between Llanfyllin as well as Llansantffraid-ym-Mechain on the B4393 road. Historically it was part of Montgomeryshire. Afon Cain runs through the town. It has a population of less than 500. Llanfechain can mean "parish or church (llan) of the Cain valley" (from Llan ym Mach Cain meaning "church in the field or plain of the Cain" to Llan ym Mechain and afterwards Llan-mechain, which comes to be Llanfechain as a result of the usual mutation of'm' to 'f' in Welsh). Nevertheless, it could likewise indicate "tiny (fechan) church or parish (llan)". Spellings of placenames vary considerably in time, so small variants such as chain/cain and also fechain/fechan are plausible. The name in the type Llanveccheyn is first experienced in 1254. It has also been referred to as Llanarmon-ym-Mechain, ym-Mechain refers to its location in the middle ages cantref of Mechain, hence 'Church of St Garmon in Mechain'.
