The Big Y-700 DNA test, described as the world’s most comprehensive Y-DNA test, can reveal common ancestors across the paternal line and has been embraced by clan societies around the world in their search for ancestral lines. The Big Y-700 DNA test has been pioneered in the United States of America by a laboratory called Family Tree DNA. Its Scottish Y-DNA Project alone has over 11,000 members and is overseen by six administers and co-administrators. “The test most people might take is an autosomal DNA test which provides information about different ancestral lines and appeals to a wide audience,” he says. We genuinely didn’t know if we were Irish or Scottish.”The breakthrough came from the Big Y-700 DNA test.
