安格尔顿

安格尔顿 transliterates 'Angleton'. The most famous bearer is James Jesus Angleton, the legendary and paranoid CIA counterintelligence chief from 1954 to 1974, recurring across spy literature and film (e.g. Robert De Niro's character in 《特务风云》/The Good Shepherd is partly modeled on him). 安 'An', 格 'g(le)', 尔 the standard '-r-' filler, 顿 '-ton' — a near-universal mapping (Newton 牛顿, Clinton 克林顿, Hamilton 汉密尔顿).

顿 (dùn) is the surname-suffix workhorse for English '-ton' endings. Train your eye: foreign-name + 顿 ≈ '-ton'.
