HARTRUM / HOTRUM One-Name Study

DNA Testing

Few of us are entirely comfortable with the genealogical research we and others have done. Many of our findings have words like “probably”, “may”, “perhaps”, and “assumption” inserted because of our doubts. We've exhausted all the traditional research tools and all that remains is using simple, painless DNA testing to provide the answers for which we've been hunting.

DNA testing is the newest tool available to genealogists. Y-DNA testing helps genealogists verify their paternal ancestry (father's father's father, etc.) in a quick and easy way. It saves time, prevents mistakes,and provides invaluable data that can be obtained in no other way. The only cost is for the testing itself, and even though it may at first seem expensive, it is probably much less than many research trips we have made that produced far less information — consider the costs of gasoline, tolls, parking, photocopying, meals, and perhaps an overnight stay.

You simply swab the inside of your cheek a few times in the comfort of your home. Mail the sample to the testing company, and then sit back and wait about six weeks for the results. You will receive a handsome certificate displaying your genetic profile — a series of numbers that are meaningless by themselves, but they hold the key to your paternal ancestry and, when matched against the profiles of others, can yield information that can be obtained in no other way. Those numbers will be compared against fast-growing databases, such as at Y search, and you will likely find other individuals whose results match yours — if not immediately then in future years. You will be notified as new matches occur.

Note that only a male with any of the subject surnames may participate in Y-DNA testing but, if you have this ancestry, you can be represented by even a distant cousin whose name is Hartrum, Hotrum or similar. Maternal ancestry (mother's mother's mother, etc.) testing can also be performed and is termed Mitochondrial or mt-DNA testing, but obviously it is used to verify other than the surname line — see below. For further information about DNA read Charles Kirchner's Introduction. Further questions and concerns are answered at Family Tree DNA's Frequently Asked Questions' page.

The following four trees show where we know we have living male individuals that are candidates for Y-DNA testing. First we need to determine the haplotype of each tree — this is basically the common Y-DNA pattern for all members of one tree. To accomplish this we first test 2 males that are the most-distantly related in each tree. So, for example, in Tree 1 we should test one male from Conrad's branch and another from Frederick's. If comparison of these tests shows that they are the same pattern, then that would confirm that result as the Y-DNA pattern (or haplotype) for George's tree. If they are not the same then one or more individuals would need to be tested to identify where the error is located. Each tree's branches will be coloured red when they have been confirmed by DNA testing. This will provide an indication as to the status of our testing.
Once a haplotype for a tree is determined there will be no need for further testing of that tree's individuals unless it is otherwise needed to verify doubtful links.

Our Discoveries so far
Simply by testing 2 individuals we have proven that the HARTRUMs and HOTRUMs are close relatives. The DNA test results for an individual from Tree 1 (a Hartrum tree) match those of an individual from Tree 4 (a Hotrum tree). This also means that their DNA pattern is the haplotype for both of these trees and so, as stated above, there is really little need to test further individuals of these two trees — even though it would be nice to confirm the relationship of the Michigan Hotrums. These results also showed a match with an individual with the surname of HARTIMAN. However, because this individual only had 12 markers tested it is not known whether this is a recent or ancient relationship.

The other interesting discovery is that so far there are no matches with any other "Hart*" surnames, such as Hartman, Hartranft, etc. So suggestions that our surname is derived from those appear to be invalid. As more people around the world get their DNA tested we expect to discover close connections with other surnames — hopefully discovering our original ancestral surname.

Even though we have many more separate trees in this One-Name study, only the four below are known by us to contain living male descendants. If your branch of the tree is not shown in the following tables please contact us so we can include your family in the tree. If you would be willing to provide a donation to support our DNA project then please go to Family Tree DNA and contribute to the HARTRUM Surname Project. Payments can be made securely via credit card or PayPal.

If you would like to participate by having your Y-DNA tested then order a test kit and mail your sample to Family Tree DNA. Note: We recommend having a minimum of 37 markers tested initially. In return you will receive comprehensive details of the results of your test — see sample reports.

Mitochondrial DNA (mtDNA) testing provides the female line (maternal) haplotype. While this is not normally used in a "Surname" project, we are using it to discover the parents of some female Hartrums that were born in the 1800s. Doing this is quite complicated as it entails discovering living descendants of those females via a pure female line (except for the person being tested) — so the tested person's mother must be related through her mother, and so on, back to the female Hartrum.

All information about living individuals is kept in the strictest confidence.

Go to the One-Name Study introduction page.

To see the listings of individuals in the Hartrum/Hotrum Family Tree use one of these links:: The Hartrum/Hotrum Family Tree pages — start with the Surnames page and click through to pages for each individual.; or . . . . . . browse the Hartrum/Hotrum Dynamic Family Tree. Wait for a tree icon to appear between the dots then click on that icon. Then wait further for the database to load — indicated by your web browser. (I know . . . that's why it's called the World Wide Wait!!)
With the latest Java update you may need to double-click the tree icon. If it still doesn't work it's likely because you don't have Java installed, or you have "active content" restricted by your web browser — see if your browser is displaying a security message below its "Address" line.
