JulesBarr on Family Tree Circles

I am looking for the line of John SWAN 1816-1904, married Hannah Porter 1845 in Newport, Monmouth, Wales. They had three children, Edwin, Mary Ann and Robert. Im trying to track Roberts family as there's some confusion about the names of his children. He married Gwenny Jones and they had Earnest, Bob (robert?), George, Jack? any info would be greatly appreciated, thankyou : )
