In this context:
- A is the successor to B
- A is the successor of B
I'm fairly certain that the first one is correct. If so, then how come we say: Mother of God, instead of Mother to God?
However, maybe can it vary on specific choices of A and B?

I would recommend using successor to when talking about succeeding a person, and successor of when talking about succeeding a position
Though both are correct in all situations, I find that I use B's successor combined with an appositive far more often.
