All Harwood, Horwood, Harrod, Harod, Herward, Herod, and similar surname males in America, the British Isles, and around the world, are cordially invited to take the Y-DNA test and join this new Harwood Family History Y-DNA Study. Female Harwood descendants and male Harwood descendants not having the Harwood surname are also cordially invited to participate and join in advancing the Study by encouraging their Harwood-surname brother, uncle, cousin, etc., to submit a simple cheek-swab test. NOTE: This Study may have funds available from time to time to contribute toward testing costs for certain Harwood lines not previously tested and for special lines where a second test is being sought. Please inquire if a group contribution is available for your line. We recommend the y-dna test be at least 37 markers. The more markers, the better the bang for the buck. The 12-marker test is too general to be very useful for genealogical dna tracing, and typically needs to be upgraded to at least 37 to provide enough specific data. The 67-marker and 111-marker tests have progressively more accurate and specific reaches back into Harwood Y-DNA history.
