Albion, nice and a reasonable amount of pocket locations

Albion and Alba have the same root it appears. Love a bit of Wiki eh

The term first appears in classical texts as Ἀλβίων Albíōn[5] or Ἀλουΐων Alouíōn (in Ptolemy's writings in Greek), and later as Albion in Latin documents. Historically, the term refers to Britain as a whole and is ultimately based on the Indo-European root for "white".[6] It later came to be used by Gaelic speakers in the form of Alba (dative Albainn, genitive Albann, now obsolete) as the name given to the former kingdom of the Picts which when first used in this sense (around the time of king Causantín mac Áeda (Constantine II, 943–952)) had expanded. The region Breadalbane (Bràghad Albann, the upper part of "Alba") takes its name from it as well.

Probably named 'White' isles because of those famous white cliffs when approached from France i.e. a Roman name. Bet them Gaelics up northern Scotland would hate this.
