Out Of Luck
During the final season of the show, the producers did try to introduce a new, neighboring family: The Kelly’s. In fact, there was even an entire episode which was dedicated to the Kelly’s – with the hope that it could become a spin-off. Alas, it didn’t work out.

During the first phase of casting, it was the kids who were chosen – well before mom and dad. So the goal was to actually cast all 12 child actors but in reserve: three blonde girls, three brunette boys, three blonde boys, and three brunette girls. Interesting.
