Have you hit a brickwall in your family history research? Do you want to exchange information with others interested in the Crum/Krom family genealogy? The Crum/Krom family DNA project may provide you with the information you are seeking. Molecular genealogy can help break down those brickwalls and connect you to others who share your ancestry. It is the latest tool available to family historians. Molecular genealogy uses Y-DNA test results to find those with the same surname who share a common ancestor. The submitters with a match can share their research results and help one another expand their family tree. The test is quick and painless. It involves ordering a kit from Family Tree DNA. The test kit contains a cotton swab which the participant rubs along the inside of his cheek. The swab is returned to the lab and in several weeks the results are mailed to the participant. The participant can then check the Family Tree DNA surname website for particpants who match their DNA test results. Only those partipcants who have given permission for others in the surname project to contact them will have their contact information posted.
