Please e-mail me at Bulldog248@aol.com and I'll invite you to my Strader Family website and you may be able to see just where your husband's family line fits in. I have over 300+ Strader's at the site.
My lines connect with the Highsmiths from Thomas Highsmith Harris, who married Martha Skiles and was the son of William Harris and Nancy Highsmith, daughter of Thomas Highsmith. William and Nancy Highsmith Harris came to Dallas County with the Skiles family (some time in the 1850s, I think). I believe they lived in Warren County Kentucky and had lived in North Carolina before that. My Moores and Lewises are from South Carolina. (I do have Floyds and Finleys from Illinois, however.)
I noticed that you are researching Highsmiths. I have a line of Highsmiths from Kentucky who came to Texas. (I also have Lewis and Moore lines that are two of my main areas of study, but I imagine the odds are against these being connected to your lines. Mine came from South Carolina to Texas.)
