Hi Christine, and thank you for introducing yourself in our g2g forum.
We need a little more information about Robert Banastre before we can answer your question. Do you have a birth and death date for us? If you found him on WikiTree, perhaps you have his profile number? All of this information will give us a better understanding of the person you are trying to confirm information on.
Once again - welcome to WikiTree. We are all very interested in helping you discover information on your ancestors. I hope you love it here as much as I do.
