I have acquired the 1900 IA Fort Dodge City, Webster Co IA that shows Charles B. St Clair and family that I believe is the family that I needed. That census shows the following family:
Charles B; Jan? (unreadable?) Frank P; Florence; Charles; Chas B (believe should read Carl B); Blossom.
I am not aware of the other two Charles St. Clair listings but would be interested in that information.
Thank you for you help and sorry for not replying sooner. I have been on vacation.
