There is a lot of information about Daniel Lee Simpson and the Simpson family in Ohio, Tenn, and Texas on newspapers.com. Too much for me to copy and send. You can get a free two week access to newspapers.com.
Hope this helps
Dear Ms. Toste,
Thank you for posting your request on History Hub!
The Federal Government does not ordinarily create or maintain birth, death, marriage or divorce records. Such records are made and kept by State and local governments rather than the National Archives. For his birth certificate, we suggest that you contact the Ohio Department of Health and for his death certificate, please contact the Tennessee Department of Health.
We hope this is helpful. Best of luck with your family research!
