We need Tweedys (by any spelling) to participate in DNA testing. Our goals are to locate the Tweedy family in Scotland and Ireland and reconnect with our kinsmen there. We have five or six Tweedys that have DNA tested to date and two paternal lines have turned up in the tests.
We urge Tweedy men to do the Y chromosome DNA test and men and women with Tweedy ancestry to do the Autosomal DNA test. Only Tweedy men may do the Y-DNA test because the Y-chromosome is only passed from father to son. We use Family Tree DNA labs for our testing.

We urge Tweedy men to do either the 67 or 111 level paternal Y-DNA test.
