How about a handcrafted family tree or personalized family crest? You could commission a local artist to create a beautiful piece of art that showcases your friend's family history and heritage. Another idea is to make a donation on behalf of your friend to a heritage preservation organization, such as the National Trust for Historic Preservation, to support their efforts in protecting important landmarks and buildings. You could also consider gifting a personalized book on the history of their family name and heritage.
Or you can get her/him a star map with the date of the wedding.
