question
grammar translation
How do I say "Who is the tallest in your family?"
You would use の instead of に here (linking two nouns), so 家族の中.

You also want to insert a superlative (phrase that means "most"/"best"/#1).
One example is 一番（目）. There are many others, like もっとも, だれより（も） (less common),
etc.

So something like:

> 家族の中で一番背が高い人は誰ですか。

For some basic examples of superlatives, see [this

answer
1. Generally speaking **に** is used to mark a place in space or time, you'll want to use **の** in **家族の中で**.
  2. i-adjectives(形容詞) are followed immediately by a noun, therefore **高い誰ですか** which is followed by a "question word" is not grammatically correct.

If you want to be polite use this:

> 御家族で最も背の高い方はどなたでしょうか？

if not, the answer above is best.
