Frederick Fitz was born ca.1750-55.It is presumed that his father was Johan Peter Fitz, an immigrant from germany who arrived in Philadelphia in 1750.Frederick had two brothers, Baltzer (Balthasar) and John (Johnannes); and two sisters, Elizabeth and Mary.
Frederick married a woman by the name of Elizabeth (last name and date of marriage is unknown).They had eight children; John, Samuel, Barbara, Nancy, Susanna, Elizabeth, Maria and Peter.Susanna married Henry Schell sometime between the years of 1821-25. The source for this information is Sylvia Fitts Getchell's book FITTS FAMILIES (FITTS, FITZ, FITTZ) A GENEALOGY, published by Capital Offset Co., Concord, N.H. in 1989.
There are numerous entries in the York County records of deeds, taxes, and probate relating to Frederick Fitz.Frederick was a farmer (as were his brothers) who bought and sold land on numerous occasions.His will was dated 1815 and was probated on March 12, 1817.
Unfortunately, I have no other information regarding Susanna.Hope this was of some help.
