Modern invented name; possibly a blend of Amber and Berlin.
Anberlin is a contemporary American coinage without a singular ancient root. It is most widely recognized as the name of an alternative rock band from Florida, which the lead singer stated was a name he had written down before the band formed. It likely draws phonetic inspiration from the gemstone name Amber and the German capital city Berlin.
