Lewis Surname DNA Testing

Started in 2003 by John Lewis and Bob Ford and assumed by Janet Lewis Crain in 2005, the Lewis Surname Y Chromosome DNA Project is in the top 20 surname projects at Family Tree DNA. Only males carry the Y chromosome; therefore a surname DNA project is an excellent way to trace surnames. Due to the fact that the Lewis surname encompasses the English and Welsh Lewis lines, as well as the French Louis lines and some German and Jewish surnames shortened to Lewis, a wide geographic area is represented. Many persons bearing these surnames are now found in Australia, Canada and the United States as well as the rest of the world. 

The LEWIS Surname DNA Project was created to develop a collection of various Lewis family groups who descend from male Lewis ancestors. ALL LEWIS lines are included, regardless of variant spelling or different surnames carrying a Lewis bloodline. All biological Lewis males are included. DNA analysis provides a tool for identifying participants who share a common male ancestor; and, when used in unison with documented Lewis pedigrees, can also aid in establishing links between Lewis groups who previously were thought to be unrelated.

Haplogroups found in the project

The Lewis DNA Project divides its participants by matches. Family members and close matches are grouped. Non matching participants are in a no match group until such time as a match or matches occur. They are then moved to the appropriate group. Adoptees and others have found their true ancestry using this genealogical DNA test.

The LEWIS Surname DNA Project has almost 1,000 members!!! And is in the top 20 projects at Family Tree DNA.
