Afon Meillionen
river in Gwynedd, Wales

Afon Meillionen (Welsh for Clover River) is a small river near Beddgelert in Gwynedd, north-west Wales.
It flows down Cwm Meillionen, a small valley which lies on the north-eastern side of Moel yr Ogof (655m). Much of the river's catchment area lies within Beddgelert Forest. The first recorded use of the name Afon Meillionen being used to refer to the river was between 1898-1908.
Afon Meillionen is a tributary of the Afon Colwyn, which itself joins the Afon Glaslyn in the village of Beddgelert.
"Meillionen" is also the name of a farmhouse in the Cwm and of a small halt on the Welsh Highland Railway between Caernarfon and Porthmadog.

Why this record matters
The phrase “river in Gwynedd, Wales” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Place names and jurisdictional language are key evidence: both can reveal earlier catalogue descriptions and overlooked record series. The source revision retrieved here is dated Nov 10, 2024. The linked authority identifier is Q4689343. Authority coordinates are 53.021, -4.123. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1898 and 1908.
Modern boundaries and familiar names can conceal earlier jurisdictions or structures that do not align with the present site. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
