My daughter from my 2nd husband has a crush on my first husbands son that he had with his second wife. I am his first wife and we had 3 children together.

Is my daughter from my second husband related in any way to his son from his second marriage. The only thing that they have in common is they both share sisters and a brother from mine and his 1st marriage to each other.

So confusing...
Thanks for any input...

No, the 2 children that you speak of have no shared blood.

No, these children are not related.

No relation.

I had to draw a diagram to figure this out.

The two children you speak of are not related. They have no bio-parent in common.
