Oke lets start from the beginning:

Emma and Bealfire are his parents. Snow, David, Rumpelstiltskin and Mila are his grandparents. King George is his greatgrandfather. Regina is his adoptive mother.

Now the tricky part: Because Emma is Henry's mother and Snow is Emma's mother, Regina is therefore Henry's greatgrandmother, because she is also Snow's stepmother. Cora would be sort of his grandmother(or greatgreatgrandmother) because she is Regina's mother.

I hope you understand it haha
