Moody在英语只是作为姓，并没有这个名（first name）
Moody这个姓起源自13世纪的爱尔兰，英美的词典对于这个姓是这般描述的。
Moody: A family name. Nickname for a courageous, arrogant, or foolhardy person, or one quickly moved to anger, from Middle English modie ‘impetuous’, ‘haughty’, ‘angry’ (Old English mōdig ‘brave’, ‘proud’, from mōd ‘spirit’, ‘mind’, ‘courage’). This English name has been established in Ireland since the late 13th century
牛津大学出版社专门出版过一本《A dictionary of first names》的工具书，是列举全部“名”的字典，当中找不到Moody.
