McLaughlin Surname DNA Project- Background
Laughlin, Locklin, Loughlin, Macklin, MacLachlan, MacLachlane, MacLauchlan, MacLauchlane, MacLaughlan, MacLaughlen, MacLaughlin, McCloughan, McGlothlin, McLachlan, McLaughlan, McLaughlen, McLaughlin
McLaughlin, Maclaughlan, McLauchlin, MacLachlan, McGlothlin, Loughlin or any reasonable spelling variation are welcome to join the project. Only males have Y-chromosomes, so only male McLaughlins (or variants) can participate. If you are female, you can have a male McLaughlin relative submit a sample for your line. For best results, testees will need to share their direct male line ancestry back to the earliest known McLaughlin (excluding living persons).
