Since surnames are passed down from father to son like the Y-chromosome, this test is for males taking a Y-DNA test. Females do not carry their father's Y-DNA and acquire a new surname by way of marriage, so the tested individual must be a male that wants to check his direct paternal line (father's father's father's...) with a Y-DNA12, Y-DNA37, or Y-DNA67 marker test. Females who would like to check their direct paternal line can have a male relative with this surname order a Y-DNA test. I was the only child born to my mother by Robert Samuel Thompson.
