Census 1920, as I read it, says Iba Richardson. Born in the right state and is right age for Isabella, so I believe Isabella to still be the wife. They have Herman Richardson listed as son living with them, age 26. He is not their biological son. Must be a nephew or cousin. They have three children: John W., Alma P., and Violet M. if you bump into them. I'd like to know what happened to them, but not necessary. Thanks again for Gibson assistance!
