Geneology?

Question

What would my step-father's son's daugher be to me? Are there any relationship calculators on the web out there?

Answer 1

Step niece  I suppose.

Answer 2

You just put "Step" in front of everything and note there is no blood tie. If you like them, you drop the "step" in all but formal introductions. If you don't, you put a slight stress on it so people know you aren't related to the girl who is chewing with his mouth open.

step-father's son = your step brother

daughter = your step-niece

When (if) you have children, they will be step first cousins to the young woman.

Answer 3

Perhaps your step-niece, right?

Answer 4

She is not related.

As your step father's son is your step-brother, you can be called her step-aunt, so you could call her your step-niece !

Answer 5

No relationship at all, except to be polite.
