Hello Sandy, I too have a Boyd family in my tree, but not by the names you have listed. Sorry! I'd like to thank you for mentioning about the smallpox outbreak in Audrain in 1860. I had no idea about this outbreak until I read your post. My great-grandmother died in Oct. 1860 at a young age. Maybe this was the cause of her death. Again, thank you for the history lesson. If I find any of your Boyd family, I'll notify you.
