The Rentz Family Project is open to all those who can trace (or suspect a relationship to) the Rentz/Renz families of Swabia (Baden-Wuerttemberg), Germany. All variant spellings are welcome. If your surname is missing and you feel it should be included, we'll be glad to add it. By sharing information and results of DNA testing we hope to grow in understanding our common heritage. If your yDNA matches a project member’s yDNA results, you are also welcome.
