The Holland Family DNA Project

Utilizing the science of DNA testing and analysis to determine one's family background is called anthrogenealogy.  When traditional methods of research hit that "brick wall" and you can't take it back any further, Y-chromosome DNA testing may help in identifying new branches of your family tree.  The Holland Family DNA Project, administered by Family Tree DNA of Houston, Texas, was created to take advantage of this new scientific approach, in an attempt to determine which Holland family groups are related and have common ancestors. 

Scientists have discovered that the DNA in the Y-chromosome, found only in males, is passed from father to son, virtually unchanged, except for rare (and random) mutations.  By testing these chromosome segments, it is possible to determine if two or more living males are related, and approximately when they had a common ancestor.  It's genealogy by genetics, and it's fun! 

The Holland Surname Project includes the surnames Holland, Hollan, Hollans, Hollen, Hillen, and Hols. Other closely related names are welcome to join our group.  According to the U.S. Census Bureau, Holland was the 249th most common surname in the United States in 2000, the most recent census for which such data is available, up from 256th in 1990. There are 125,987 people in the U. S. with the last name Holland. 

 

Family Tree DNA

Family Tree DNA of Houston, Texas, in conjunction with the University of Arizona, has been selected as the vendor for the Holland Family DNA Project.  As project administrator, I recommended that you view their website at www.familytreedna.com and become familiar with their methods of research.  They distribute the test kits and lab results. 

Family Tree DNA, as of September 2010, has over 191,550 records in their database of Y DNA results, and over 6,000 Surname Projects (of which this is one) which include over 98,000 surnames.  The Holland Family DNA Project, initiated in November 2003, has 118 participants of which 83 kits have been returned, and includes 6 surnames. 

Family Tree DNA, as of December 2005, has over 48,000 records in their database of Y DNA results, and over 2,500 Surname Projects (of which this is one) which include over 26,000 surnames.  The Holland Family DNA Project, initiated in November 2003, has 19 participants which include 4 surnames. 

If you are a male with the surname of Holland, Hollan, Hollans, Hillen or other related surname, you are invited to participate in this project.  The testing is performed by Family Tree DNA.  You can participate in this project by getting a group rate.  Prices have come down since this project started.  I prefer you get pricing information directly from Family Tree DNA since they change from time to time.  As the group administrator, I do not receive any compensation of any kind.

Which test should you get?  As the number of markers tested goes up, and the price goes up, so does the accuracy of prediction go up.  All genetic tests from Family Tree DNA will provide you a probability that you and another person, who has an exact match, will have your Most Recent Common Ancestor (MRCA) within a range of time backwards. The 12-marker test gives you a range of 14.5 generations (50%) likelihood & 48 generations (90%) likelihood. With the 25-marker test, the 50% likelihood drops to 7 generations and the 90% to 19.8 generations. The 37-marker test tightens further to 5 generations (50%) and the 90% to 16 generations.

37/37 Your perfect match means you share a common male ancestor with a person who shares your surname (or variant). Your relatedness is extremely close with the common ancestor predicted, 50% of the time, in 5 generations or less and with a 90% probability within 16 generations. Very few people achieve this close level of a match.

67/67 Your perfect match means you share a common male ancestor with a person who shares your surname (or variant). Your relatedness is extremely close with the common ancestor predicted, 50% of the time, in 3 generations or less and with a 90% probability within 5 generations. Very few people achieve this close level of a match. All confidence levels are well within the time frame that surnames were adopted in Western Europe.

Family Tree DNA's names for the tests and test names you may see that are used by the lab:

Common test name: Lab name for test: Description:
Y-DNA12 STR first 12 markers
Y-Refine12to25 PP3 the upgrade from 12 to 25 markers (next 13 markers)
Y-Refine12to37 PP5 the next 12 markers that upgrade to 37
Y-Refine37to67   markers 37 to 67
mtDNA HVR1 tests the female lineage of females and males
mtDNARrefine HVR2  
  SNP stands for single nucleotide polymorphism; its sole purpose is to establish definitively to what haplogroup one belongs
mtDNA H sub-clade    
  RFLP RFLP stands for restriction fragment length polymorphism
     
     
     
     

By now you surely have many more questions than I can answer.  There is a FAQ page at FamilyTreeDNA's web site that answers most questions you may have on the tests.

If you decide to test, be assured that your privacy will be protected.  You decide if your results are to be known to others.  The project administrator is Diana Holland Faust.
