All main branches have been entered back to the earliest ancestor listed in the family histories for that line as shown in my original family tree rebuild post here.
I am sourcing information from A Genealogical History of the Kolb, Kulp, or Culp Family for individuals also listed in A Genealogical History of the Hunsicker Family. Once I have completed this I will begin sourcing all of the original documents I have plus documents I can easily acquire from places such as Ancestry.com.
As I have added the information from the various family histories I have noticed that even though the source is original (despite the fact that I have copies that have been reproduced either on paper or electronically (or both)) I have come to realize that the information is secondary (not primary) in that the authors were reporting second hand information that they found in their research without citing the source. Therefore, until I find a primary source or several different secondary sources (not another family history) of information I will consider these facts as unproven.
