How about a DNA test kit from a reputable company like Ancestry or 23andMe? This would allow your grandson to learn more about his ethnic background and possibly connect with distant relatives based on shared DNA results. Alternatively, you could also consider getting him a subscription to a genealogy website like MyHeritage or FindMyPast, which would allow him to research his family history and build out his family tree. Both of these gifts would be fun and educational for someone who loves genealogy.
Or you can get him a star map with the date when he was born.
