Maybe this will be of interest to researchers of the Sweatt family. On the website "Tracking Your Roots" I found the following message in the section on Covington County, Alabama and in the document "Births, Deaths, & Marriages from Covington Co., AL Newspapers":
"Interest Notice: To all whom it may concern: This is to certify that we have know the SWEATT family for number of years and find by tracing history and from our own observation that they are originally from France. Their foreparents on father's side from France, on mother's from old Holland. The late A P SWEATT, father of Chas P SWEATT married a lady whose mother was of Indian Blood.
