Good day. I have a Great Uncle Andrew who died during ww2, and my Nan’s name was Alice Viola Thornhill (now Brown, but she has since passed away). The other names you mentioned also sounded like family members based on what I remember my Aunt and Mom told me. Except the details seemed a little off from what I was told during covid when I first saw this. I was supposed to reach out at the time, but with everything going on during covid, this slipped my mind until now. If your still interested and looking for info, please reply back, and I’ll see if I can setup a conversation with my mom and Aunt.
