Canterbury Stained Glass

I came across this image in a book about English stained glass windows. It's from Canterbury Cathedral and shows the three youngest daughters of Edward IV - Anne, Catherine and Bridget. The hair maybe tends more to blonde than red, especially the one on the left as we look, however they were all daughters of Elizabeth Woodville and she was a redhead. The image was created in the 15th century, but the heads were renewed in the 18th century.

Incidentally, the Wikipedia page on Catherine shows a larger version of this same stained glass image, which depicts another two of Edward's daughters. However, the description states that it depicts Elizabeth, Cecily, Anne, Catherine and Mary ..no mention of Bridget.
