DBCC’s aim was to give the constituencies names which reflected the areas they cover, and where there was no name in common use for the area, to use the names of the parliamentary constituencies.
Nod CDFfC oedd rhoi enwau i’r etholaethau a oedd yn adlewyrchu’r ardaloedd y maent yn eu cwmpasu, a lle nad oedd enw cyffredin i’r ardal, i ddefnyddio enwau’r etholaethau seneddol San Steffan.
