I hadn't heard of Motherless Daughters but I think it's a wonderful idea. I am very lucky to still have my mother who is almost 96, although she is fading, so my heart goes out to those who've lost their mums. I still miss my beautiful friend Belinda sooo much, and can't imagine how hard it must be for you as her daughter, Caroline. All the very best for your walk!!! Sending loved and hugs. :)
