肯尼思 is the standard Mainland transliteration of the English name Kenneth. The friendly nickname Ken is rendered separately as 肯 (Kěn). Famous bearers include 肯尼思·布拉纳 (Kenneth Branagh, the British actor and Shakespeare director).
memory
Three syllables map cleanly: 肯 kěn ('Ken-'), 尼 ní ('-ne-'), 思 sī ('-th'). Mandarin has no /θ/, so 思 sī (think) is the conventional stand-in for English '-th'.
