If you have this relationship:
People::HouseID = Houses::HouseID
Then Go to Releated Records from a layout based on the Houses layout should bring up a found set of records on the people layout of all people linked to that house.
Go To Related Record [Show only related records; From table: People; Using layout: "People" (People) ]
Ah! I didnt have the option to "Show only related records" checked. That seems to have fixed it. Thanks!
