Audric (AW-drik for English speaking, OH-drik for French speaking, OW-drik in other select countries) is a medieval French name, from the Old German masculine name Alderich, meaning "old ruler." It comes from the Germanic elements ald, "old," and ric, "ruler." A mere 27 boys were given this name in 2015. It is a variant of the earlier form Aldericus, which was a saint name. Aldric is another form, given to 8 boys in 2015, with a 9th century saint namesake. Elderich/Eldrich was another spelling variant, as was Eldric, given to 6 boys in 2015. It is not uncommon to see the letter k at the end of these names - Audrick, Aldrick, Eldrick, Elderick, etc.
The specific spelling of Audric gives us one namesake: Audric del Vilar, lord of Auvillar. We know that he was a troubadour and that he may have raised one of the earliest known troubadours - Marcabru.
Move to the spelling Alderic and you will find just a couple namesakes, including a Canadian politician and a politician from Quebec. In the U.S. Alderic hasn't been used since 1924, given to 5 boys, but before that it had only been used in 1914 and 1916.
