All BARKER descendants are welcome to join the project, but since only males have Y-chromosomes, only male BARKERS can participate in the testing. If you are female, you can have a male BARKER relative submit a sample for your line and/or you can discuss your Barker pedigree in our Activity Feed in order to share it with others. It is important to provide your Earliest Known Ancestor (EKA) so that others can make a connection to your line.
