Project Background 

The GUIN, GWIN, GUYN, GWYN DNA Project was established by former group administrator & genealogist Michael A. Gwinn, ret. USN, AT1(AW) on July 2011, to February 2018 in search of his own genetic connections, with a purpose to bring everyone together through a dedicated study of our common and similar surnames.

Prior to the advent of Y-DNA testing many Guins, Guinns, Gwins and Gwinns in North America believed they were of Welsh descent (primarily because of similarity to the Welsh word gwyn) and then discovered through Y-DNA testing that they had ancient Irish origins.  This was especially true of those who tested positive for M222 or what is commonly known as the Northwest Irish Modal Haplotype. 

At that point in time, there were a few Guinn members in the GUNN Project, a few Gwinn members in the WINN Project, and several Guinns and Gwinns in the QUINN Project.  Many others did not belong to any project.  In addition, those that had tested positively for M222 were denied entry to, or removed from, the Wales Y-DNA Project. 

Since 2011, the GUIN, GWIN, GUYN, GWYN DNA Project has grown steadily in membership to where, as of December 2020, the Project has over 370 members and continues to grow.  The different surnames of those participating in the project are numerous and include surnames such as Goins, Guinan, McGuinness, and Winner (to name just a few) that are likely of a separate independent origin.  However, these members are valued and no project members are given preference over another based on their surname.  The project is diverse and has a membership that, while largely North American, have historical or ancient origins in Ireland, Wales, Scotland, England, Continental Europe and Africa.  It can be anticipated that future members may also have Native American origins.
