How about a personalized book that tells the story of her life and family? There are many companies that offer custom-made books that include personal photos and details of one's life. Alternatively, you could consider a subscription to a storytelling podcast, or tickets to see a professional storyteller in action. If your grandma is interested in writing her own stories, you could also gift her a nice notebook and some fancy pens to inspire her creativity.
Or you can get her a star map with an important date you share.
