What is my niece's husband to me?
Your niece's husband is your nephew by marriage — some families say 'nephew-in-law,' though no formal term exists. He married one generation below you, into your niece's seat. Any children the couple has are your great-nieces and great-nephews by blood, no 'by marriage' about it.

Nephew by marriage
English has no single formal word for this relative — “nephew by marriage” is the label genealogists use.
- You
- Your niece
- Her husband
From the other side, you are their aunt or uncle by marriage.
This connection runs through a marriage, not a shared ancestor, so the ancestor chart can't draw it.
