There was a man who contacted me because he had a DNA match with my Uncle. He is the only DNA match that my uncle has had! But this man knew that his grandfather( if I rememberit right had been adopted about 1870. I would have to look up all the back paperwork to remember the particulars. What research that we tried to do gave him a possible match with a Jacob ( Irick surname version) The man lives in New Jersey area I believe. Have you had a DNA test taken for your Irick's? If you are interested I can forward his e-mail to you. Our Irick is a G haplogroup.
