DNA testing is the newest tool available to genealogists. These tests help genealogists verify

their paternal ancestry (father's father) in a quick and easy way. It saves time, prevents

mistakes, and provides invaluable data that can be obtained in no other way.

 

The results of participating members that are of "Following the Rivers with the Bryd/Birds" can be

seen here. This Group is mainly working on the Byrd/Birds that are believed to be descending from

Thomas T Byrd of Robertson Co TN and beyond. Other Byrd/Birds DNA results from other areas can be

seen here: http://www.worldfamilies.net/surnames/b/byrd/index.html

ANCESTRAL SIGNATURE NUMBERS:

To determine the “modal” value for each group, also known as the ancestral signature, look at each

marker in each group and decide, based on the results, what would most likely have been the original

result for the shared common ancestor for each. 

 

Next is to highlight the places where any of the group members has a different result from the signature. 

This makes it easier to quickly spot any mutations. For example, we see at a glance that B-46 and B-44

share the same mutation at marker 464c. They are more tightly related to one another than to the rest of

the group because they share a common ancestor who experienced that mutation.

 

MUTATIONS::


A heritable change that may occur in a gene or in a chromosome, and may take the form of a chemical

rearrangement, or a partial loss or gain of genetic material leading to a different number of repeats

of a certain sequence or change of one of the bases in a sequence

 

Mutation rate :


The rate at which a mutation can happen. Although mutations happen randomly in time, and one can see a

mutation happening today between a father and son, different studies show that mutations normally

happen every 300-500 generations. A mutation rate of 0.003 means one mutation every 333 years (1/333

equals 0.003)
 

MARKERS:

 

The DYS#'s in red have shown a faster mutation rate then the average, and therefore these markers are

very helpful at splitting lineages into sub sets, or branches, within your family tree. Explained another

way: If you match exactly on all of the markers except for one or a few of the markers we have determined

mutate more quickly, then despite the mutation this mismatch only slightly decreases the probability of

two people in your surname group who match 11/12 or even 23/25 of not sharing a recent common ancestor

 

Marker 464 is a special marker, and you may notice that not all the highlights of the differences are

marked in the same way that the other markers were highlighted. This is because nearly all men have

four copies of marker 464. Each copy may have a different value, which is why we may see different

numbers for each. These values are listed, a through d, from the smallest number to the largest number.

Distance Relatedness Explanation
0 Related Your perfect 25/25 match means you share a common male ancestor with a person who shares your surname (or variant). These two facts demonstrate your relatedness.
1 Related You share the same surname (or a variant) with another male and you mismatch by only one 'point' on only one marker. For most closely related and same surnamed individuals, the mismatch markers are usually either DYS 439 or DYS 385 A, 385 B,389-1 and 389-2 from our first panel of 12 markers, and on the following from the second panel: DYS #'s 458 459 a 459b 449, 464 a-d, which have shown themselves to move most rapidly. The probability of a close relationship is very high.
2 Probably Related You share the same surname (or a variant) with another male and you mismatch by two 'points' among the 25 markers we tested. For most closely related and same surnamed individuals, the mismatch markers are usually either DYS 439 or DYS 385 A, 385 B,389-1 and 389-2 from our first panel of 12 markers, and on the following from the second panel: DYS #'s 458 459 a 459b 449, 464 a-d, which have shown themselves to move most rapidly. The probability of a close relationship is good, however your results show mutations, and therefore more time between you and the other same surnamed person.
3 Probably Not Related You share the same surname (or a variant) but are off by 3 'points' or 3 locations on the 25 markers tested. If enough time has passed it is possible that you and another distantly related family members' line each have had a mutation, or perhaps 2. The only way to prove that is to test additional family lines and find where the mutation took place. Only by further testing can you find the person in between each of you... this in 'betweener' becomes essential for you to find, and in their absence the possibility of a match exists, but further evidence should be pursued.

Distance Relatedness Explanation
0 Very Tightly Related 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. All confidence levels are well within the time frame that surnames were adopted in Western Europe.
1 Tightly Related 36/37 You share the same surname (or a variant) with another male and you mismatch by only one 'point' at only one marker--a 36/37 match. It's most likely that you matched 24/25 or 25/25 on a previous Y-DNA test and your mismatch will be found within DYS 576, 570, CDYa or CDYb. Very few people achieve this close level of a match. Your mismatch is within the range of most well established surname lineages in Western Europe.
2 Related 35/37 You share the same surname (or a variant) with another male and you mismatch by only two 'points' --a 35/37 match. It's most likely that you matched 24/25 or 25/25 on previous Y-DNA tests and your mismatch will be found within DYS 439 or DYS 385 A, 385 B,389-1 and 389-2, from our first panel of 12 markers, or from within the second panel at DYS #'s 458, 459 a, 459b, 449, or within 464 a-d. If you matched exactly on previous tests you probably have a mismatch at DYS 576, 570, CDYa or CDYb in our newest panel of markers. Your mismatch is likely within the range of most well established surname lineages in Western Europe.
3 Related 34/37 You share the same surname (or a variant) with another male and you mismatch by three 'points' --a 34/37 match. Because of the volatility within some of the markers this is slightly tighter then being 11/12 or 23/25 and it's most likely that you matched 24/25 or 25/25 on previous Y-DNA tests. Your mismatch will most often be found within DYS 439 or DYS 385 A, 385 B,389-1 and 389-2 from our first panel of 12 markers, or within the second panel: DYS #'s 458, 459 a, 459b, 449, or within 464 a-d. If you matched exactly on previous tests you probably have a mismatch at DYS 576, 570, CDYa or CDYb in our newest panel of markers. Your mismatch is likely within the range of most well established surname lineages in Western Europe.
4 Probably Related 33/37 You share the same surname (or a variant) with another male and you mismatch by four 'points' --a 33/37 match. Because of the volatility within some of the markers this is about the same as being 11/12 and it's most likely that you matched 23/25 or 24/25 on previous Y-DNA tests. If you matched exactly on previous tests you probably have a mismatch at DYS 576, 570, CDYa or CDYb in our newest panel of markers. If several or many generations have passed it is likely that these two lines are related through other family members. That would require that each line had passed a mutation and one person would have experienced at least 2 mutations. The only way to confirm is to test additional family lines and find where the mutations took place. Only by testing additional family members can you find the person in between each of you...this 'in betweener' becomes essential for you to find, and without him the possibility of a match exists, but further evidence must be pursued. If you test additional individuals you will most likely find that their DNA falls in-between the persons who are 4 apart demonstrating relatedness within this family cluster or haplotype.
5 Only Possibly Related 32/37 You share the same surname (or a variant) with another male and you mismatch by five 'points' --a 32/37 match. It is most likely that you did not 12/12 or 24/25 or 25/25 in previous Y-DNA tests. If several or many generations have passed it is possible that these two group members are related through other family members. That would require that each line had experienced separate mutations and one person would have experienced at least 2 mutations. The only way to confirm or deny is to test additional family lines and find where the mutation took place. Only by testing additional family members can you find the person in between each of you...this 'in betweener' becomes essential for you to find, and without him only the possibility of a match exists, further evidence should be pursued. If you test additional individuals you must find the person whose DNA results falls in-between the persons that are 5 apart demonstrating relatedness within this family cluster or haplotype.
6 Not Related 31/37 is too far off to be considered related, unless you can find an “in-betweener’ as for determining ‘Only Possibly Related,’ above. It is important to determine what set of results most typifies the largest number members of the group you are 'close' to matching. You may be 31/37 with an individual, but 34/37 with the center of the group, and your potential relatedness to him is through the center of the group.
