The project is intended to document information about the Riehle surname (or closely related surnames) including: • Y-DNA diversity and commonality among people with the Riehle surname • Details about various Riehle family contingents: - Y-DNA information related to each family contingent - For those in the Americas, identity of immigrant ancestors, from where they emigrated and where they settled. - For those in Europe, location of historic and current geographic pockets associated with the Riehle surname - Where adequate information is available, the interconnection of family contingents: • Between and among previously disconnected family contingents in the Americas • Between continents • Details of Y-DNA mutations and related migration patterns through the millennia along with best available explanations about what brought these ancestors to Germanic Europe The project serves as a link between the genetic genealogy website www.riehle.net and the more purely genetic science resources available here at Family Tree DNA.
