How about getting her a genealogy DNA testing kit? There are several different companies that offer them, such as 23andMe or AncestryDNA. These tests can help your grandma learn about the origins of her ancestors and possibly connect with living relatives she didn't know about. Another idea could be to hire a professional genealogist to help her research her family tree, or purchase a book about genealogy research techniques to help her improve her skills in this area. Additionally, you could consider arranging a visit to a local genealogy library or museum, or a subscription to a genealogy magazine or website that she would enjoy.
Or you can get her a star map with the date when she was born.
