The comprehensive family history from 1729 onwards by Beulah Hicks Blair "Some Lineages o Berks County" was compiled after much original research into church records, land records, wills, etc., and she also had access to family archives in PA. She is certain there were two sons o Hans Jobrich, rothers, Johann 1725-1782, married to Anna Barbara (Schermann), settled in West Berks County, and Johann George, 1727-1812, marri to Susanna Culp, settled in East Berks County, and she documents these extensively in the book. There is no other way to distinguish these two wives; it appears settled that there were two families. Some decades ago I went through all the local histories and similar records and found some corrections and additions could be made just from those records sourced from the principals who provided the information for local histories, but in general she may be relied upon unless found inconsistent. No one in any of the three major on-line genealogical compilations I have seen provides proper consideration of her findings, relying apparently upon genealogies which conflate these two persons in the absence of access to Blair's book.
