My wife's cousin is descended from Reverend Pierre Robert via (2) Pierre II, (3) Jacques or James, (4) John, (5) Mary Harriet and Richard Bostick. We have been working for several years on a book that explores Richard Bostick's ancestry and descendents. I am currently working on the Robert Family chapter and have gathered a great deal of background on Jean (John) Roberts, son of Reverend Pierre. It sounds like you are descended through John's lineage. You may have interest in our work product. I would be happy to share a draft of the Robert Family chapter, if you are interested.
