Thanks so much for responding, Pat. I am acting for my husband's half-sister, Jan Louise Brock Hetherly. Yes, her father's parents are as stated.Lillian lived with her son, Gordon Brock, (and Jan) during her last years. I knew her well. Jan has absolutely NO information on her Brock heritage, and I have promised to help her. We would so appreciate any information that you would share. Please respond to me by email, and I would be so happy to send my address and phone. We live in McKinney, and Jan lives in Ft.Worth.
