About us

Several distinct, unconnected Cooley clans have emerged through DNA testing. For example, at least seven separate DNA signatures are found among the so-called Dutch Cooleys. In fact, the DNA for the Dutch Cools/Kools/Coles has no resemblance to any tested Cooley family.

Please be advised to contact an admin before testing. We know which test will best fit your objectives and which tests would provide largely redundant results.
