It should be sufficient to add it in the Bio. Marriages- 1st Marriage, the date, location, to xxxx b xxxx d xxxx---2nd marriage, the date, location, to xxxx etc... The Death date and date of remarriage will say it all. I have a case of a split, where no divorce has been located, and the one spouse found a partner. The partners lived together and had 12 children.. They married after the death of the first spouse. Their marriage occured just before the first of their children got married. Family tradition says they married to legitimize their children. We all have similar confusion that is hard to address in a profile. I'm glad we have a Bio where we can handle the odd information.
