Okay, follow along.

I said: "I was explaining that in fact TWO daughters married Galbraiths. Your Ona Artileen was never mentioned to be one of those daughters."

That literally means No one ever said Ona was one of the daughters who married a Galbraith. It doesn't mean that Ona was not one of Dock's daughters. Your entire problem in this thread is that you didn't understand where the Galbraith name came from and why we were discussing a Galbraith in connection with a Mary Alvey.

It can get confusing when trying to follow where other posters are going in a long thread with links that you might not be fully understanding. You can admit that.

And you are welcome for all the work done to find Dock's parents just as you requested.
