A DUKE Family History and Y-DNA Genealogy Research

Family history from Belfast, India and England and my Y-DNA research from father to son.

DAGLISH DNA Project (FamilyTreeDNA)

The main known branches of the Daglish family originate from County Durham and Northumberland in the United Kingdom, and most living Daglishes can trace their ancestors back to these English counties. Through the DNA project we hope to look at these different branches and compare for common ancestors.The surname directories show Daglish as a variant of Scottish names Dalglish or Dalgliesh - but so far it has been difficult to confirm this through standard family history research; we hope the DNA project might help to provide the answer.The DNA test works on the Y-chromosome which is passed down through the male line (in much the same way as surnames). The Y-chromosone is likely to remain unchanged for many generations, but occasionally the code will 'mutate' creating small differences, and this is also useful for family history. For testing we therefore need living male members of the Daglish family. There is another DNA test which follows the maternal line - but this is not directly relevant for our study.

DALE Project (FamilyTreeDNA)

To determine the parentage and ancestry of those named Dale, Deale, Dail, Dial, Dyal and variants

DANIEL DNA Project

Using Y chromosome DNA testing to determine the relationships between men with the surname Daniel, and variant spellings including Daniels, Dannel, Daniell, O'Daniel, McDaniel, etc. The goals of the project are to determine the relationships between families in the United States and other countries and to trace the lines of participants to related lines in Europe.

DAVENPORT Surname DNA Project

The purpose of this project is to determine possible relationships between different DAVENPORT family lines (worldwide, not just the US). DAVENPORT, DEVENPORT, DANFORTH.

Dean Surname Y-DNA Project (FamilyTreeDNA)

The purpose of this project is to facilitate placing orders for Y-DNA test kits to be used by males surnamed Dean and to coordinate the results from those tests. Using these results may enable us to reinforce or disprove theories regarding our male DEAN ancestors. We also hope to build a Y-DNA database which will enable us to identify various DEAN ancestral lines. At present we have 111 subjects in the surname project: 30 with no matches and 18 groups with two or more matches. This makes 48 distinctly different genetic lines with the surname Dean or a variation of Dean - amazing!

DeGRAAF DeGRAFF Genealogy and Y-DNA

The DeGRAAF and DeGRAFF (plus various spellings) Surname DNA Project was initiated to help identify and group our family lineages. This is a newly formed group. We are looking for additional participants. Individuals interested in collaborating on family history and using genetic testing to assist our research efforts are encouraged to join. If you are a male with one of the included surnames and are interested in researching your direct paternal line further, you can participate. This project study is using the DNA test that looks at a portion of the DNA called the Y chromosome. The Y chromosome is unique to males and can be used to identify one's direct paternal line. For this reason females cannot contribute directly but can find a male relative (father, brother, cousin, etc) to be tested as a representative of her line. Additionally, anyone related to a person with a surname who is included in our surnames of interest and willing to share their paper trail ancestry findings are invited to join. Visit our site and click 'Request Membership' to join. Our surnames of interest include; DEGRAAF, DEGRAFF, DE GRAAF, DE GRAFF, DE GRAAFF, DEGRAAFF, DEGROFF, DEGRAF, DEGRAEF, VAN DE GRAAF, VAN DER GRAAF, DE GRAFFE, DIJKGRAAF, GRAAF, DYKGRAAF.

Desmond DNA Project (FamilyTreeDNA)

DESMOND is the name of a place in Ireland. "Desmond" is the Anglicized spelling of the Gaelic "Deasmhumhnaigh", which roughly translates to "south Munster". The ancient boundaries of Desmond included most of today's County Cork and County Kerry, in the province of Munster. The origin of DESMOND when used as a surname is less clear. There are three competing theories: 1) Families using the DESMOND surname are descended from the Gaelic sept "Ui Deasmhumhnaigh" which means "man of south Munster". 2) Families using the DESMOND surname are descended from the "Earls of Desmond", a branch of the Anglo-Norman FitzGerald family, who settled in Ireland in the late 1100's, and a noble line which officially died out in the early 1600's. 3) Families using the DESMOND surname are descended from another Gaelic sept or septs (such as MacCarthy, "Kings of Desmond"), and are part of a sub-clan which took the surname at some point during the middle ages. Each theory has its strengths and weaknesses, and its possible that any number of the three theories account for the ancestry of modern-day Desmonds. The Desmond DNA Project will attempt to determine thru Y-DNA analysis which of the DESMOND surname origins are true

DEVINE Surname DNA Study

The study includes families that bear any variation of the surname Devine, including Divine, Devine, Diven,

DEWEES(E) Surname Project (FamilyTreeDNA)

The principal goal of the Dewees(e) Surname Project is to use Y chromosome variations in Dewees(e) males to test the hypothesis that virtually all Dewees(e) families in America are descended from a single ancestral male, most likely Garrett Hendricks deWees, who came to America in ca 1663.

Dewhurst Family DNA Project

A collaborative effort linking various branches of the Dewhi/urst surname back as far as we can go - even to Viking roots! Test results will be posted, compared and associated to family trees where possible to show likely familial connections.

DICKASON/IN/ER/ENSON/DIXON DNA Project (FamilyTreeDNA)

Surname Project including 25 Y-DNA testers. Many spelling variants. Five distinctly separate groups of DICKASON & variants. Most from England. Link also to excellent DICKASON name history. See also separate DIXON Surname Project.

DILLMAN DNA Project

DIMMETT Worldwide Family Project (FamilyTreeDNA)

Currently testing anyone with the surname DIMMETT. All spellings of the surname are welcome. We are trying to determine if all spellings are connected or not, as well as learn where our ancestors may have come from. To learn more or participate, please visit our project.

DIXON DNA Project (FamilyTreeDNA)

Surname DNA project for DIXON, DICKSON, DIXSON, or any reasonable variant.

DORSEY DNA Project

This project is open to any male with the surname Dorsey, Darsey, Dossey, D'Arcy or other variant spellings. Objectives: To determine whether the surname Dorsey has one or several origins and whether families with the surnames D

DOSS DNA Project

Several English and Germanic Doss families have emigrated to America in the past 400 years. The Doss DNA Project

DREWRY / DRURY Surmane DNA Project (FamilyTreeDNA)

The DREWRY DNA project welcomes all who are interested in better defining the relationship between DREWRY / DRURY families.

DUBOSE-DUBOIS Surname y-DNA Project

DUBOSE, DUBOIS, DUBOISE, DUBOICE, DUBOYS, DUBOSC, and other surname variants are welcome to join this Y-DNA paternal project. Many people with these surnames descend from Isaac DUBOSC and Suzanne COUILLANDEAU, French Huguenot refugees who settled on the Santee River in South Carolina in the 1680s...or from sons of Chretien and Cornelia DuBOIS, also Huguenots who emigrated to America in 1660 and settled in New York. This project is intended to provide additional research alternatives for connecting the many branches of these Huguenot families.

DUNBAR DNA Project

A worldwide project to determine the various DUNBAR family lines and how they are all related, including those who descend from Gospatric.
