Awww hon that's too sad and I'm sure something your granny wouldn't have wanted to see happen. One of my family members did a lovely thing after my grandmother passed. She took a beautiful photo taken at her 80th birthday party and had it copied. Also another picture of grandma and grandpa during a lovely cruise they took after he retired (he passed 10 years before she did). Set of those were sent out to everyone and it really was such a lovely thing to do. Those pictures are some of my most treasured possessions (the one of my beautiful grandmother sits on a special shelf right beside my computer so I feel she's always watching over me ).

Maybe you can do something similar to help your family remember her and the bond she would want you all to treasure even after her passing.
