Oddia would be the Aunt of my Grandmother. Guess that would make her my 2x Great Aunt.
When she died, she left money to each of her siblings. One of the siblings was Hugh O., my 2x great grandfather. Hugh had passed before Oddia, so Walter sent a copy of the will to my grandmother, who passed it on to me. I have a copy of it on my family tree if you would like to see it.
I'm not sure how you would go about doing that. Please let me know if I can help in any way.
