Answer:

All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad, sallallaahu ‘alayhi wa sallam, is His Slave and Messenger.

The daughter of a man's sister's husband, from another wife, is not included in the women who are forbidden for marriage, and thus it is permissible for him to marry her as long as there is no other impediment that prevents that.

Allaah Knows best.
