The best way to help with the research on those Hebridean families, who descend from the Ardnamurchan Mac Eain family, is to participate in the DNA test. Six families have been located, all are a DNA match to each other and to the already test Mac Dónaill chiefs. All located and ancestry confirmed via DNA testing. One of these families is a Johnston from Islay, so we may have located the DNA pattern of the Ardnamuchan Mac Eain family. We expect this because they match a known descendant of the Glencoe Mac Eain, their close cousins. Anyone with an interest in participating in the test can visit the web site listed below to find out how. http://freepages.genealogy.rootsweb.com/~mccaindna/ The Mac Eain families are McCain group 03 in the results page. Anglicised surnames are two McCains, two McKanes, one McKean and a Johnston. Barra McCain McCain DNA Project
