If there is a chance some of your family came to Texas, you may want to check this index. This Index to Texas Probate Records currently contains 26,000 names records that date between 1836 and 1940.
To those that visit the site, I ask only that you take a moment to send a note to the high school students who worked on this project. The students attend McNeil High School which is part of the Round Rock Independent School District in Williamson County, Texas. (Central Texas - just north of Austin)
