Several weeks of research have failed to produce any significant
information on the goddess Agrona, whose name is preserved in that of the
River Aeron in Ceredigion (Dyfed), Wales. I have only an etymological
confirmation and a brief mention of a "Washer of the Ford" story which is
placed on the Aeron. No one else - including university libraries and
museums - have been able to provide details.
Can anyone help? Your assistance would be greatly appreciated.
