Our Family descends from the TENNISON family of St. Mary's County, Maryland. As the family migrated west a large portion of the family used the surname DENNIS. Although we have found numerous family members we still have several missing branches. There are also DENNIS or TENNISON families hoping to link to a family. So we have provided enough information for those searching their family line to see if they might link to us. The use of DNA has helped a lot of families find a link. Recruiting male family members to take DNA test is the second reason for this web site. THIS IS A WORK IN PROGRESS---Check back. We will not only present information on the different branches in our large family but provide migration information on the many descendants. We will be reporting on the results of our DNA tests (no personal information). We will examine the markers that link different cousins to each other. Before you try to search our database, please read our HELPFUL GUIDE to UNDERSTANDING our WEBSITE and the charts provided below.
The DNA project is sponsored by Family Tree DNA, (www.FamilytreeDNA.com). We are known as DENNIS Group 3 and the only group that has had males with the surname TENNISON to test into their family group. We have 26 males that have tested. Of those, we know the full line from the 1600"s to present day of 7 men. We have another group of 3 that are close "cousins" to each other and hoping for that final link to find out which TENNISON is their ancestor. We have another group of 4 men who use the surnames TENNISON, TENNIS, and DENNIS in our family. We need more family members DNA to help connect them to a certain branch within our tree.
