As well as Wes Switzer in his genealogy "Switzer all My Fathers Were" showing Johann Christopher and Catherine to have eight children, Eula Lapp in her book "To Their Heirs Forever" lists the following: "Family changes - marriages, deaths or removals - altered the complexion of the community on the Southwell Estate greatly in the 1740's and 50's. In the Switzer family of Courmatrix, for instance, the father, Christopher, who had come from the Rhineland, died in 1755. In this family were four boys, followed by four girls. Of the girls, only Margaret (later Mrs. Philip Embury) lived to maturity. In 1750, her three-year-old sister, Christine, had died. In 1755, the year of the father's passing, this family lost another small daughter, aged about six. The first girl - also named Margaret - had been buried early in 1743, the same year that the second Margaret was born. Following these tragedies, Margaret Switzer must have been especially dear to her mother and brothers, Tobias, John, Martin and Peter - the latter most important to our story. (Mrs. Switzer had been Catherine Ruckle.)" The above does not prove that there wasn't a child born earlier, but it would seem that Eula Lapp, during her 12 years plus of research for her book, obviously did not find anything leading to a daughter Julianna/Joanna.
