Hi there and thank you for the note. I do not know of an Etta Dalby in our side of the family, eventhough I can't imagine that there are "that many" different lines of Dalby's in the state of Oklahoma. The name Dalby is just not "that" common of a name.
I have got to find a report that I had been given - back in the early 1980's (probably 1980) that confirms who we are and where we came from. The report is "safely" hidden in my garage - hadn't looked at it in ~15 years - but I need to locate it so I can add some real substance to this website's endevor.... as far as where I came from.
Good luck in your search - sorry I wasn't much help - please keep in touch,
