The Ulster mitochondrial DNA project is a sister project to the Ulster Heritage Y Chromosome DNA project. With Y chromosome research only men participate, because the Y chromosome is only passed from father to son. This makes it idea for surname research. With maternal DNA, both men and women carry this, so both can participate in the test. Many advances have been made in mtDNA testing in the last few years. It is an excellent way to do family research, locate cousins, and explore one's ethnicity. It can also be of help in surname research, as a match can clarify from which branch of a family one belongs. This can allow a researcher to use research from a collateral line that has a better paper record.
