Hi Darlene: I'm thinking we may have a connection. My ears (eyes?) perked up when you mentioned the SINN name (because I also have that name in my family) and now the connection to north of Stuttgart. I visited the area last year (Unterheimbach to be exact), and have some information regarding the MOLL, KAIM, HÜBNER, MUGLER, SINN, SCHÄUFLER, UTZ, and LEDERER connection (who are all interrelated). These are all names of the people who built the Unterheimbach Lutheran Church in 1757. I show a Katharine Sophie SINN married to a Philipp Wilhelm MOLL around 1865 in the Neckar region of Württemberg. Let me hear from you if you are interested.
