How about a personalized heritage preservation book? You can include pictures of their favorite historical places, artifacts, and important dates in their family history. You could even make it an interactive experience by asking them to contribute their own stories and memories. Alternatively, you could sponsor a heritage preservation project in their name, perhaps through an organization like The National Trust for Historic Preservation. This would allow them to directly support the preservation of a historic site or landmark. Another idea is to give them a handmade item, perhaps a pottery piece or a piece of art, that has been created using traditional techniques or materials that are part of their cultural heritage.
Or you can get her/him a star map with an important date you share.
