Thomas Davenport was born about 1620 in England. He arrived in Dorchester (Boston), Massachusetts prior to 1639 becoming a freeman in 1642. He is believed to have married Mary Pitman. They had nine children – Sarah, Thomas, Mary, Charles, Abigail, Mehitable, Jonathan, Ebenezer, and John. Thomas died in Boston in 1685. His descendants settled in Connecticut, Massachusetts, New Hampshire, Vermont, and Rhode Island.
The Thomas of Dorchester Line is one of four American Davenport lines that have been determined, by Y-DNA testing, to descend from the ancient Davenport line of Cheshire, England.

Thomas of Dorchester Branches
Relationship Tree – How the participants are related.
The following are the known male branches of the Thomas of Dorchester line. 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 do not have test participants. Of course we will accept any Davenport participants but especially need the non-highlighted branches.

Y-DNA Test Results
| The descendants of Thomas of Dorchesterย belong toย Haplogroup R–BY269248 –ย Note: The Y-DNA of the Thomas of Dorchester Davenport line is very similar to three other American lines and those of English origin. This means that these groups are all related somehow.ย These are the Y-DNA results to-date of the participants descended from Thomas Davenport. The different row colors represent the separate branches of the line.ย Click on the Kit # to view more information about the individual Davenport linage.ย Newer results have aย purpleย block to the left of the kit number. Theย Modalย haplotype is what we believe the Y-DNA of Thomas of Dorchester looked like based on current results.ย ย Redย andย blueย cells show where an individual varies from the modal.ย Redย indicates movement upward, whileย blueย downward. Combined pink cells represent “connected” markers where the actual difference is counted as one. |
