He is the only child in/of his family.用in还是of

He is the only child in / of his family.

这句话中式用 in 还是用 of?

都可以，in侧重范围或地点，of侧重归属或所属。如：

She is the second child in the family. 她在家排行老二。《现代汉英综合大词典》

She is clearly the most articulate and self-possessed member of her family.显然，她是全家口才最好、最沉着冷静的人。《柯林斯高阶英汉双解词典》
