About Your U5 mtDNA Haplogroup Project Administrator:

Please note: The project administrator is a volunteer and does not work for Family Tree DNA, DNA Heritage, Relative Genetics, or any other testing company.  I do not receive commissions or compensation of any kind.  I volunteer because I care about genealogy, and I want to help you use DNA results to help make genealogical connections.

Linda Thompson Jonas      

     has been conducting full-time genealogical research for more than 30 years.  She is a former president of the British Isles Family History Society-U.S.A. and is co-author with Paul Milner of A Genealogist's Guide to Discovering Your English Ancestors (Betterway Books, 2000) and A Genealogist's Guide to Discovering Your Scottish Ancestors (Betterway Books, 2002). 
     Linda specializes in finding immigrant origins.  She is a former volunteer at the Immigrant Genealogical Society and was a staff trainer at the Los Angeles Family History Center.  Linda is frequently consulted to read old handwriting and to translate genealogical records of numerous languages. She lectures on all aspects of immigrant research including passenger lists, naturalization records, and more.  She is particularly sought for her expertise in finding the origins of Colonial Americans.  
     Linda Jonas lives within a few miles of Washington, D.C. and frequently researches in the Library of Congress, the National Archives, the DAR Library, as well as repositories in Maryland, Pennsylvania, Virginia, and Tennessee. 
     Linda is a regional coordinator for the International Society of Genetic Genealogy [ISOGG], and is conducting several DNA projects of historical importance. She is co-administrator for the Thompson DNA Project (a surname project) and for the British Isles DNA Project (a geographical project). She is uniquely qualified to help participants use DNA with traditional genealogy to find the origins of their ancestors. 
     Linda is currently the Director of the McLean [Virginia] Family History Center which specializes in colonial immigrant ancestry.   She is the immediate past President of the Mount Vernon Genealogical Society.
