Invited: Men surnamed GRADEN, GRAYDON and similar spellings. A discounted Y-DNA test cost is available to group members (see order form below). The GRADEN/GRAYDON group is attempting to link families with similar surnames. Y-DNA matches have been established between ten families tracing to the following locations in Ireland: Co. Fermanagh (circa 1630-1850), Cos. Dublin/Kildare (circa 1640-1850), and Co. Wicklow (circa 1790-1860). In earlier years, these families may have resided in the Borders area between Scotland and England (pre-1600). Two different Y-DNA patterns have been discovered for several Graydon families tracing to Sunderland, England, and several Gradon families tracing to Durham, England.
