Historical Pony: Gremlin

Gremlin is a matriarch of the current herd. She was born in 1979 and died in 2000. Her sire was the bay pinto half Arabian Gordo and her dam was an unnamed dark chestnut who currently has the nickname of Gremlin's Mom. Gremlin's 1992 foal was Surfer Dude and he was his mother's son when it came to color.

She was a chestnut and would have tested as e/e. Gremlin was in the herd of the solid chestnut Simon for about 10 years so all of their foals were guaranteed to be chestnut. There's not enough info to guess her agouti status since only one of her known foals wasn't a chestnut. Surfer Dude's sire Broken Jaw was a bay, but he and their other two foals were also chestnut. Her last foal, born in 1999, was black.

Gremlin is the source of splashed white 1 in the Surfer Dude/Riptide family. There's obviously no color tests for these ponies but we can figure some things out using observation. Her expression of splashed white was a stripe and two socks, but she had several flashy foals with solid colored stallions. Splashed white came from her sire Gordo. He had other descendants who also seemed to have it. Multiple descendants of Gremlin have tested to have splashed white 1.

Two other things that make her descendants well known also appear to have come from Gremlin. The dark sooty chestnut she inherited from her dam was also passed down to her stallion son. She wasn't as dramatic of a blonde as her son and his son, but she was flaxen too. Neither sooty or flaxen is testable but we can see how it's genetic in this family.
