I show Anna Margaretha as being born 1748. But no other dates or marriage. You can be quite certain that she was the daughter of Hans Martin, as the Hans Martin family name was spelled both Troester and Trester on various documents at the time. You can learn more about Hans Martin and the different spelling versions of the Treaster name, as well as records of Anna Margaretha, in the early history pages at www.TreasterFamily.com
Hope this helps answer some questions for you! Would love to hear more from you if you can find info of Frantz Hautz.
