Dear Lilyliac
I am also researching my Hosack ancestors, by marriage. My family were the Tinnings of Tinwald, my great-great-great Grandfather was James Tinning, the brother of Jean Carruthers Tinning who married John Hosack of Glengaber. James' father, John Tinning was married to Mary /ann Graham of Cannonbie, Dumfrieshire and they had at least eight living children.
I have come to this late, so may have missed you ... hope not!
Jenny
