Hi there,

I just want to ask you to be careful copying names in from Wikipedia, particularly regarding name:cy. 

The Welsh Wikipedia uses their own style for place names, which is unofficial and not to be used. Any occurences of "Feneswela" may have stemmed from this.  The official name for Venezuela in Welsh is Venezuela. 

This is the source to use, it's from the Welsh Government and it is compatible with OSM licence:

Diolch
