Based upon the information contained on CD100, Automated Archives, inc, Automated Family pedigrees, I originally had Alice as the mother of Peter's children, but changed that based upon Bernard Burke, Dormant and Extinct Peerages, Burke's Peerage, Ltd., London, 1883, p. 206, Fitz-Herbert, Baron Fitz-Herbert, who states Peter "m. 1st Alice, dau. of Robert Fitz-Roger, but by her had no issue."
