Hi Julie-Ann: I have looked through my files and, although there is a similarity of names, I do not think we are from the same family, except perhaps several generations further back. The use of traditional Scottish naming pattern can be a help or a hindrance, the latter because of cousins having identical first and last names , compounded by the absence of the mother's name in some earlier Parish registrations. Alexander, William & Robert were names frequently given to Woodburns, while Agnes & Janet were often given to Mitchells. I am sorry I could not be of help.
However, there is one piece of family lore you find interesting and may connect with, and that is our supposed relation to George Woodburn the Covenantor/martyr? Who at one time was a tenant of Loudon Mains (farm).
Good luck,
Ian
