My Welsh expert friend says that the term "church" as a meaning of Llan may not be correct, as many of the places that use it are often pre-Christian. He suggests that "the settlement of" may more correct.
Most likely correct. Found this old etymological dictionary;

Llan, from Old Welsh Lann
On page 101 of the above.
lann n f "church church-yard" [llan]
IE *lendh- "freies Land, Heide Steppe"
lann (2) n "frying pan"
Etymologically identical with "lann (1)"
The abbreviation IE means Indo European and the German text meaning "free land", "Pagan" and "Grassland (Steppe)", certainly fitting in with the idea of pre-Christian era, though Old Welsh dates from 800-1200AD and this word appears in all Brythionic Languages therefore probably *much* older.
The Welsh Language Wikipedia page for "Llan" states:
Mae gwreiddiau'r gair yn hen iawn. Yn ôl Geiriadur Prifysgol Cymru mae'n deillio o'r gair Celteg tybiedig *landa o'r gwreiddyn *lendh- 'tir agored, rhos'. Cytras iddo yw'r gair llannerch a'r gair Saesneg land. Yn yr ieithoedd Celtaidd eraill ceir geiriau cytras, fel lann ('eglwys; rhos, tir agored') yn Llydaweg a lann ('tir; adeilad, eglwys') yn y Wyddeleg, er enghraifft. O'r gair Galeg cytras *landa ceir y gair Ffrangeg lande ('rhos, tir garw').
Ie: Extremely old word, tir = land, agored=open, rhos=rose. Also occuring in Breton (Llydaweg), Irish and French - possibly from Gaulish/Insular Celtic. Eglwys however is a word for Church but comes from the Latin for church...and that's another etymological story*
No idea about lann (2) above ... might refer to the shape of land/area - a flattened bowl - Welsh does describe some geographical features in terms of shape.
Mods: can we change the title of the forums to RailUKandCelticLinguisticForums ... ?
