This DNA Project is a study into the genealogy and DNA markers of persons with ancestors who had the surname of Hollingshead and variant spellings.  It is intended as a research work to try to distinguish which genetic lineages can be linked to genealogy and historical records of this surname.  While any type of DNA test (Y-chromosome, Mitochondrial, or autosomal DNA) is eligible to join, the primary means of the administrator's research is the Y-chromosome because it provides genetic markers that span deep into chronological time with enough variation to be able to distinguish lineages.

Where the Project Administrators can plot a latitude and longitude position for the described earliest known ancestors, we may do so in order for the project mapping to have the most comprehensive display possible and our plot may be different and overwrite a geographic plot made by the project member.

Also note that in order to gain new insights, participants should be willing to share their results in a de-identified manner on the project web sites.  It is a two-way street, we gain a wider perspective and genealogy insights on our individual heritage but also help other researchers connect and clarify their heritage through reciprocity and friendliness.
