Oh my goodness this post is so old, I do hope my reply finds you. Your 'Ella' (I have her as Ellen) is my 3x'x Great Aunt. Her sister, Agnes Hannah Clark, is my Great Great Grandmother. I do have additional family information if you are interested. Please message me if you get this as I would love to share what I have and see what you have. My tree is private for various reasons, but would be happy to allow you access.
