London Welsh

To mark St David's day I thought I might do a little something on the four roads here in Childs Hill with Welsh names. It is the biggest concentration of such names in London. Elsewhere you will find one or two Welsh names but never, I believe, as many as four. Aral tradition suggests that they were given by a Welsh builder. There is still a Welsh builder nearby (D W Bevan) though that is probably a coincidence. The Welsh have been in London for centuries and there is no concentration of Welshies in Childs Hill or any other one area. The names of the streets are

Llanelly Road, Llanvanor Road, Crewys Road and Nant Road

The first (pronounced Lanuly locally) suggests a Llanelli connection. The second is perhaps the name of a farm. The third is a main road in Cardiff (there is no 'e' in the Cardiff version. It is pronounced Crooz locally). The fourth and most interesting is the Welsh for brook or stream, and indeed there is one although it is now almost entirely underground.
More interesting again is the fact that near Cross Ash in Monmouthshire, there is a small settlement called Llanfaenor with both a Nant Farm and a Great Crwys Farm too. There is a Llanelly not too far away. Perhaps that Welsh builder was from the same corner of Wales as me.
The local residents association is called CLAN after the three main streets of the four.
