Gruffudd, Heini, Welsh Personal Names, Y Lolfa, 1980. An inexpensive book on Welsh names, in both Welsh and English. Its main drawback is that not all names are dated, and some names listed here are names of gods, and were not used by mortals during our period. If possible, first names in here should be checked against Morgan & Morgan's Welsh Surnames. Recommended, but use with care. (JA)
Morgan, T.J., and Prys Morgan, Welsh Surnames, University of Wales Press, 1985. An excellent book full of dated references. It has over 30 pages of general information about Welsh naming practices as well as an extensive listing of Welsh Surnames, complete with dates. Since Welsh surnames are frequently formed from given names, it can also be used to document given names. Highly recommended. (JA)
Richards, Melville. Welsh Administrative and Territorial Units. University of Wales Press: Cardiff, 1969. Everything you ever wanted to know about Welsh place names, both medieval and modern. Recommended if you need a Welsh place name. (JA)
