How Do I Show Both Parents of The Same Child

I have two tables, one with the names of adults and the other with the name of children. In the Children's table there are two columns, ParentID (Not Nullable) and OtherParentID (Nullable). I would like to query the tables so that when either of the parents IDs are presented as parameters, the other can show as the spouse or partner along with the related children from the Players table.

Is this possible with the tables I have? Or do I need to take a different approach?
