多丁顿 transliterates English place names ending in '-ington' or '-ton' — the
顿 (dùn) suffix is a near-universal Mandarin rendering of English '-ton' (compare
华盛顿 Washington,
牛顿 Newton,
普林斯顿 Princeton,
伦敦 London). There are several Doddingtons in England (Cambridgeshire, Cheshire, Kent, Lincolnshire); the name is also a surname.
