A Third Creighton?

In the last two posts, I've put up CDVs of Kate Creighton, who I think is the mother of Louise Creighton, featured in the second of the two Creighton collections. Is this a third Creighton? This portrait is labeled "Kate Creighton" but the hair is straight and a different color. I thought it might have been mislabeled, but the chin shape differs from Louise and is much closer to Kate. There is a third possibility. While it is far more common for sons to named after fathers, it's not unheard of to name a daughter for a mother. The one thing that I'm curious about is that this young lady has pierced ears. Nothing decorative about the photographers stamp on this one, so I didn't bother to scan it in. "JOHN P. ORR.
