On 15 January 1822, in the Evangelish, Schoemberg, Schwarzwaldkreis,Würtemberg, my great great grandfather’s older brother, Johann Georg Weber married Eva Katharina Kusterer. They were the parents of three children: Sabastian, Regina Anna, and Louisa.
My research shows that Uncle Georg came to the United States with Great Great Grandfather, Gottlieb (aka Goodliff), their sister, Chistianana, and their father Johann Adam. I admit to being remiss in tracking the travels of any but my direct line. Grandfather Adam Weber must have returned to Württemburg since he died there on 6 November 1849. I have no record if Aunt Katharina accompanied Uncle Georg to America.
It is hard to do a complete research of people not in your direct line. Doing those that are in your direct line is tough enough.
