Thanks for your interesting posting. I am in the throes of writing a doctoral dissertation in theology and I am racing to meet a deadline. Please give me a month or so to get back to you. Sorry I can't take time to do it just now.
I may not be much help. I'm sure you have more background on the Davidsons than I do. If I recall correctly, the name came through as Daverson in some of the records I have.
Here is my email address. Please get back in touch if I haven't responded in a month or so.
Thanks for your understanding.
