Alan (given name) masculine given name in the Welsh language; although it is not directly related to "Alan" (it is derived from Proto-Celtic "*alouno-" meaning either "nourishing" or "wandering"), today it is generally used as a variant form of the English name. An earlier bearer of this name is Alun of Dyfed, a character in the "Mabinogion". The name became popular in modern times when it was adopted as a bardic name by John Blackwell, a 19th-century Welsh poet. The short form of "Alan" is "Al". This name is a short form of numerous other etymologically unrelated names that begin with this syllable.
Meredith (given name) unfamiliar with Welsh naming conventions, and has been confused with the Welsh name "Moreiddig" (which has produced "Moredik", "Moriddik" and "Morithik"). By the early Middle Ages, the name took the form of "Mereduc", in part due to "its suitability for taking Latin case-endings". The name has been rendered into Latin as "Mereducco", "Mereduci", "Mereduth", "Mereduco", "Mereduc" and "Mereducus", "Mereducius". In the dialect of Dyfed (Pembrokeshire) the final voiced interdental fricative (represented in writing by "dd") was lost to produce the name "Meredy". Though there is no etymological connection, "Meredith" has also been equated or associated with "Merrick", "Meyrick," and "Moryce",
