No, I'm sorry. I can't help you out. I wish I could. The only Robert's I'm aware of so far in our family is a Martha Roberts and her father Doctor Roberts, and they are from a different branch of the family even. We do have Collins married into Pearson/Piersons, but not a Johnston Collins so far, although I do not have that family completed as yet. As I am researching though, I will keep your question in mind.
