"In this work, when it shall be found that much is omitted, let it not be forgotten that much likewise is performed" (Dr. Samuel Johnson, Preface to Dictionary of the English Language) .

While every effort has been made to ascertain the correctness of the information provided in this section, some of the dates, especially those of the medieval period, may be approximate. Birth dates are included for contemporary Welsh men and women whenever they have been provided. Regrettably, it is impossible to include every person who has contributed in someway to the history, culture, language, or traditions of Wales, either at home or abroad. Some names are included for their unusual character of special interest. In the Welsh alphabet, Ch, Dd, Ff, Ng, Ll, Rh, Th, andPh are considered as single letters. To save confusion for non-Welsh readers, entries follow the order of the English alphabet. The following letters do not occur in the Welsh alphabet: J, K.Q,V, X, Z. (when names begin with any of these letters, they are borrowings from English).
