Marilyn, the Crow(e) DNA Group Study has identified 19 different Crow, Crowe, Crowell, Kroh, families living in the World today.The DNA is from the living male Crow descendants that carry the male Y-Chromosome past from their forefathers down to them.
Here is a link to these families and their oldest reported Crow(e) ancestor(s) at Family Tree DNA; https://www.familytreedna.com/group-join.aspx?Group=Crow then click on www.familytreedna.com/public/CrowDNA/ , then click on results.It may take a little while to load the results page based on your Internet connection.
The popular male Y-37 maker kits are now on sale through the end of July, so if you have a living Crowe brother, uncle, nephew, cousin, from your family Crowe line that would test for you, he would likely match one of the 250+ Crow(e) testers from around the world and land in one of the 19 color coded Crow family groups the tester's represent.Testing would narrow down your research area as well as provided you and your family with possible new cousins that might have the connection, the shoe box full of pictures, or perhaps, even a family bible to get you on track to your older ancestors!
It's like a family history trip of a life time without even leaving home, and a lot less expensive!
Be careful of tests that seem to cost less and beware of how those other companies count their DYS DNA test markers!They are not as they seem to be and a lesser cost equals lesser value and information, in my opinion.
