I do believe the two ladies mentioned are the same but I'm still trying to confirm that they are the ones directly related to my grandmother. In tracing records of my grandmother, Catherine Elsie Hughes, it leads to Katherine Esther Delaney. So I'm still trying to determine how that could be the same person. I don't know much about name changes, etc. back in those days. Anyway, I hope you and your wife can help. I'll be glad to share all the info I've found on them.
