Definitely ask her. I have found in several cases, including my Grandma, and my wive's grandma, they both had the thoughts "oh, no one wants to hear those old stories" thinking the younger generations had no interest. My Grandma "never spoke" about the loss of her brother in the Philippines (Corporal Paul Warhoover, USA) until I asked her about it one day. She was still saddened about it, but was fine to talk about and she was happy to hear we had put his name on a remembrance list at the National Mall in Washington DC.
My wife once asked her Grandma what it was like during prohibition and at first got the "oh you don't want to hear all that old stuff" but then she got talking and it was fascinating.
