Today, I came across your message of Tuesday, November 14, 2000. Don't know how I missed it, when you originally sent the message.
I'm fairly sure that our "Arnall's" are connected somehow, being that they lived in-and-around Wright City. You mention that your grandfather was Frank Leroy Arnall. If had included his date of birth and date of death, it would have giving me something to work with at the Clayton Genealogy Library here in Houston, Texas. If you've made any progress, on the Arnall line, since November I'd like to hear from you. As I may be able to find additional information at the Clayton Genealogical Library.
