Concerning the writing of its name 'Ando,' in those historical records generally state as, the clan used the denomination of '安藤 (Ando) clan' during the Kamakura period to the period of the Northern and Southern Courts when the clan was settled in Tsugaru region, while it was settled in Akita region in the mid-Muromachi period and after, its denomination came to be written '安東 (Ando) clan,' and therefore, the individual surnames of the clan until mid-15th century will be written as '安藤 (ANDO)' and after that it will be written as '安東 (ANDO),' and for the sake of simplicity, the clans name will be consistently written as the 'Ando' clan.
なお、アンドウの表記について諸史料では主として鎌倉時代から南北朝時代(日本)にかけての津軽時代には「安藤氏」、室町時代中期以降の秋田時代には「安東氏」とされている例が多いことから、個人名表記は概ね15世紀半ばまでを「安藤」、以降を「安東」とするが、本稿では便宜上、氏族名は「安東」で統一する。
