Nah, we have very few writing from the Celts, but they did practice marriage and divorce (the woman took back her parents' bride price, and could divorce if her husband talked about their sex life. The husband could divorce if his wife insulted his beard). The also had concubinage contracts, probably with at least one-to-many, maybe many-to-many. It was purely legal/civil matter, because religious matters weren't written down. So marriage was in fact not religious originally. I've gotten that from Peter Berresford Ellis' books, which contains much more than that, and paint Celts as a more refined society than the greco-roman one.
