Thank you for the info and the photos, you have been so helpfull.
Yes, Lilian/Lillian has given me quite a headache putting her life together. After Walter died she had multiple husbands and children. My Nan was only a few months old when Walter died, so luckily I dont have to go too far into her other marriages/children. We didnt have any details at all of my late Nan's real dad when we started, so I'm very pleased with finding what we have about Walter.
As for William, we have quite a lot of his documents to go on luckily, so its only his military things I'm not clear on.
Thanks again for being so helpfull :-)
