Development
On April 26, 2016, Jim Miller was asked "Are Diamond Tiara's parents divorced?" and replied "Not that I'm aware of."

Season two
According to Granny Smith's tale in Family Appreciation Day, his grandfather, Stinkin' Rich, was one of the first ponies to buy Granny Smith's zap apple jam, and started a business by reselling it. In the same episode, it was told that this had helped contribute to the foundation of Ponyville.

In the same episode, Filthy Rich appears at Sweet Apple Acres to politely confirm he will receive the first one hundred jars of zap apple jam from Granny Smith, "as usual". As they walk off-screen, Granny asks him how his father is doing. He is later seen giving a presentation about "Rich's Barnyard Bargains" to Apple Bloom's class that bores most of the class to sleep except for Twist and Diamond Tiara. He is again seen at the end of the episode sternly pushing a reluctant Diamond Tiara to Sweet Apple Acres to help other fillies sing to the water in the watering cans, part of Granny Smith's special process of making zap apple jam. Despite being a rich business pony and his daughter's mean spirit, Filthy is amicable to Apple Bloom, Granny Smith and everypony else.

When Granny Smith calls him by his first name, he explains that he prefers "Rich". Cheerilee initially calls him "Mr. Filthy"; after he looks chidingly at her she immediately corrects herself, and he regains his usual easy going and calm appearance.
