Minerva was featured in only one episode (Captain Jack), as the Cleaver's housekeeper. They needed her in the plot to have someone to blame for drinking the brandy. She was never seen again. And what about the puppy Captain Jack? I don't remember seeing him again either.

I always wondered why June needed help with the laundry and cleaning since she was home all the time. Maybe if she wore some slacks rather than dresses, heels and pearls, she could get some work done!
