This group of Davenports is temporarily named "Unattached Line 1" because we don't currently know where they fit in. Their Y-DNA match each other, indicating a common ancestor, however, they do not match any other tested Davenport line so far. They all have a Davenport ancestor that resided in the Tennessee, Kentucky, Virginia area. The current belief is that they are all descendents of Joseph and/or John Davenport, non-paternal sons of Glover Davenport of Franklin County, Virginia.. 


Listed below are some of websites dedicated to researching this group of Unattached Davenports.  Each represents the complete line or information about its progenitor. If you know of additional websites that might fit this same criteria - please contact the administrator at info "at"

Kyle Davenport's comprehensive database of the Davenports in this "Unattached Line 1".

A good place to expand your research is the Davenport Archives website. It contains hundreds of Davenport related documents, photos, trees and includes lists of researchers and their interests.



The following are the known male branches of this group of Unattached Davenports. For our purposes a branch would begin with the sons of the 1st generation. If there was only one son then we would start with the sons in the 2nd generation and so on. We would like to test at lease one individual from each branch. The red highlighted entries are branches for which we have test participants. Of course we will accept any Davenport participants but especially need the non-highlighted branches.

If there are additional branches not listed or other changes need to be made - contact info "at"

The Unattached descendents belong to Haplogroup R-BY3957

These are the Y-DNA results to-date of the participants of Unattahed Line. The different row colors represent the separate branches of the line.  Click on the Kit # to view more information about the individual Davenport linage.  Newer results have a purple block to the left of the kit number. The Modal haplotype is what we believe the Y-DNA of Thomas of Dorchester looked like based on current results.  Red and blue cells show where an individual varies from the modal. Red indicates movement upward, while blue downward. Combined pink cells represent "connected" markers where the actual difference is counted as one.

 Other Surnames

In most cases when any of our Davenport results have had a high resolution (37 or 67 marker) match - it was with another Davenport. However, there have been a few other surnames that came very close to the Davenports. For our purposes, very close means they match on 33 out of 37 markers or better, or 62 out of 67 or better. The surnames listed below are those that are very close to this Davenport line on the 37 or 67 marker test.
This does not necessarily infer that they had a common ancestor. But it may be worth looking into the possibility. The first step is to determine if the ancestors lived in the same vicinity at the same time. When viewing the "prospects" - give the 67/67 a higher priority, then 66/67, and 65/67, and so on.
