I have several situations where all I know is that John Doe is married to Maria (only source for her are the baptismal records for the children), but then somebody else marries Maria, widow of John Doe. I have not created profiles for these women because I didn't want to contribute to the avalanche of "Unknown" profiles and only mention them in the bios. I am, though, slowly coming around to consider creating these profiles with LNAB Unknown when they have children with both husbands for the sake of maintaining the connection between those families.
