My only interest in this John Willison ended when I found he didn't come to this country until ca. 1870. My Willisons of Flintstone have been in what is now Allegany County, since 1755. I think your John Willison's immigration documents are available at the Allegany Co. Circuit Court. I do have a slight connection with the Willison/Walkinshaw family as they had a daughter, Martha, who married Abraham Lewis, son of William Lewis who married Ann Price, daughter of Jane Williams and William Price. Ann Price was also a sister to Sarah Price Dando, my great grandmother. Connie
