Wow, that sounds like a real field discovery! The carvings could be a visual record of lineage, maybe even showing how people married within the community. If there are repeating symbols, they might denote generations, and if any marks cluster around specific nodes, that could hint at prohibited or preferred unions—like cousin marriages in some cultures. I’d love to sketch a quick diagram and see if the patterns match any known kinship terminologies. Let me know if you can share a photo or a quick sketch—maybe we can uncover the social rules encoded in those stone lines!
