Meaning and history
Teale is a modern English given name transferred from a surname or influenced by teal, the name of a small duck and the blue-green colour named after its markings. Some surname lines may have separate geographic or occupational histories, so the nature-word explanation is not universal. The final e distinguishes the personal-name spelling but does not establish an ancient root. Reliable prominent real-life bearers using exactly Teale as a given name are limited, making a conservative modern-English description most appropriate.
