We are interested in tracing Harpers who left Ireland and Scotland over the past 400 years for Canada, USA, Australia and New Zealand to determine how many different lines there may be and how many families with paper trails that state only they came from Ireland or Scotland may in fact trace back to a most recent common ancestor. For this we need to get samples from as many male Harpers (or variant spellings such as Harpur, Harpor, etc.) to agree to be tested. The tests are non-invasive and do not identify an individual as only the Y chromosome (father to son transmittal) is tested. The cost can be made reasonable if several family members chip in.
