My what a memory you have! I found out my grandfather was not adopted. As it turns out my ggrandfather had an affair and the woman's father left my grandfather on his doorstep. Therefore I do not know who my actual ggrandmother is but I do know that the blood line is intact paternally. As far as the research you have done for me I am confused altogether. I do believe one of the twins, Robert, is the right one but if his father was the illegitimate son of Mary Corkill and this other guy then I should confirm and stop looking for Corkill's and look into this guys geneology going backwards. Am I right.
