Thea
My aunt was indirectly named after a horse, too. Her cousin was named Vera after being born the day a horse of that name apparently won the Newcastle plate, if there is such a thing, and she was named after her cousin.I also have a family in my tree where there were so many boys the parents hadn't thought of a name when the christening came round and asked the Vicar, who suggested Frederick Augustus after some royal. So the poor child was given that name, his brothers being the usual John, James, Thomas etc.
