Test Results

One reason people join a Y-Chromosome Surname Project is to determine whether other people with the same surname are genetically and/or genealogically related to them.

The first place to look for related people is to look for those who belong to the same subclade of a particular haplogroup. To learn more about haplogroups and clades, click on the button labeled Haplogroups on the left.

The first group we will look at is our most common group, the I2a1b1 subclade. Most of these members are genealogically related to each other within the past 500 years. We describe their relationship by estimating how many generations back in time you would have to research to find a common ancestor. DNA tests will not tell you who that ancestor is but will give you a statistical estimate of how many generations to the common ancestor shared by you and your potential DNA relative. This concept is called the Time to the Most Recent Common Ancestor (TMRCA). FamilyTreeDNA provides a tool that allows you to compare your Y results with someone else using this TMRCA concept.

Results for Haplogroup I2a1b1 are summarized below.

To use this chart, find two members you want to compare. For example, look at the location where the row for Ronald Teddie Alsup intersects with the column for William Lee Alsup and you will see the number 13. This means that their Y-Chromosome results were similar enough that you could expect, with an 80% probability, to find a common ancestor for them in 13 generations or less. If you assume that an average generation is 25 years, that would put their common progenitor about 325 years ago, around the year 1700. This is well within the time frame that it would be possible to find that common ancestor using standard genealogical methods. On the other hand, Ingvald Hansen, and David Peter Alsup are separated by 24 generations or about 600 years. It is not likely that they would find their common progenitor in the 1400's using standard genealogical techniques. Although they may never find out exactly how they are related, it is apparent that Ingvald's paternal ancestral line is related to the Alsup family even though Ingvald's surname is not one of the Alsup name variants.

The results from Haplogroup I2a1b1 are what your would expect from people descended from a single common ancestor several hundred years ago.

One Haplogroup member, Dale Cardon Alsop, has a documented paternal family line going back to Ashbourne, Derbyshire, England. This is important to other project members in the I2a1b1 haplogroup who have not yet traced their paternal line back to England. If your TMRCA is within 24 generations of Dale, there is little doubt that your Alsup/Alsop ancestral line originated in England in the area near the Alsop ancestral home in Alsop-en-le-Dale.

The other group with several members is haplogroup clade R1b1a1b. This is one of the most common sub-haplogroups in the United Kingdom. Results of the TMRCA analysis are summarized below.

TMRCA for Haplogroup R1b1a1b

The two John Franklin Alsip's are closely related, probably a father and son. Other than them, others are either not related at all or are only very distantly related. Members with a 24+ in the TMRCA table are likely related with a common ancestor 600 to 1,000 years ago. Only Kenneth Allsopp and and Byron Lee Alsop are related to each other within the genealogical timeframe (500 years). The three members (Joseph Charles Alsop, Daniel Jaroslav Darilek, and David Viking Alspach) who are in the other clade of the R haplogroup (R1a1a) are not closely related to each other and are even more distantly related to members of R1b1a1b (more than 1,000 years to a common ancestor). Results from Haplogroup R1b1a1b are NOT what you would expect if all of these people descended from a common ancestor within the last few hundred years.

Larry Allsup and Steve Laisure, members of the E1b1b1 haplogroup share a common ancestor within 13 generations (325 years) with an 80% confidence level. Samuel Earl Alsup, Jr., a member of a related subclade (E-PH1818) is not closely related to Larry or Steve or any other member of the project.

Bryan Lee Hyatt and Vincent Walter Spencer are members of the final subclade, J-M172. They are not related to each other nor are they related to any other members of the surname project.

One would expect that if all of the Alsup/Alsop's in the world originated from Gamellus de Alsop of Alsop-en-le-Dale, then all of the members of the DNA project would be in the same haplogroup and would be related with a common ancestor within the past 900 years or less. However, this lack of DNA "relatedness" could be the result of several factors. There may, in fact, be more than one origin for the Alsop/Alsup name. If this is the case, testing of more Alsop family members should provide more insight into Alsup origins.

Another reason for a lack of DNA matching may be an "undocumented paternity event" somewhere in the family history. This may be the result of an undocumented adoption or a birth from an unknown father. Geneticists call these "non-paternity events". I prefer the term "undocumented paternity event". Since all people have a father, the term "non-paternity" seems to be an oxymoron. Since geneticists have found that historically there has been a 2-4% undocumented paternity rate each generation, it is not surprising that many people's genetic ancestry does not match their genealogical ancestry.

In other cases, someone from outside of the Alsop family may have adopted the Alsop surname because of a step-parent relationship or may have changed his surname to Alsop to be eligible to inherit his wife's family's estate.

To see the Alsup/Alsop raw test result details (for those members who have agreed to display this data) in the FamilyTreeDNA database click here. This chart lists the project members organized by haplogroup. The names of the Y-chromosome STR markers are listed across the top. The values of the markers are listed below. The numbers indicate how many times the STR sequence at that marker repeats. The more closely the value of the markers match, the more closely two people are related. Closely related people will likely have the same values for most of the markers. This information is interesting but not as useful in determining relationships as the TMRCA analysis.
