How about a DNA ancestry kit? This would allow your granddaughter to learn more about her heritage and ancestry in a fun and unique way. There are several different kits available, but the most popular include Ancestry DNA, 23andMe, and MyHeritage DNA. These kits will give her a breakdown of her ancestry and can also connect her with other family members who have also taken the test. Additionally, you could consider a subscription to a genealogy website such as Ancestry.com or FindMyPast.com to help her further research her ancestry.
Or you can get her a star map with an important date you share.
