In regard to your Baillie line, google the Yeltholme gypsies,Scotland. Baillie is one of the predominant surnames in the towns gypsy community.
Regarding the Wilson line, I have no known connection, but may have an idea for some further research. In my locality a number of 'travelling' Wilson's have settled in both the Stokesley and Guisborough areas of North Yorkshire, the former being my old work place and the latter, my home town.
I am researching Drummond,Todd and Anderson lines, as is my very distant cousin, Tom, which are proving to be a giant jigsaw puzzle and frustrating. Let me know how you get on.
p.s my email is different from this one it's my dad's mine is email@example.com
