About this Group

This is the most ySTR diverse genetic family within Taylor Family Genes. (See the Fluxus diagram below.)

Two members were previously in a separate genetic family, designated R1b-050. However, more sophisticated analysis showed they share a common paternal ancestor within genealogic time with others of R1b-006.

Some members show great genetic separation and little probability of being related to some other members within genealogic time.  Based strictly on ySTRs, all show a high probability of being related within 24 generations to at least one other member. However, It is possible that the ySTR matches are the result of convergence, rather than shared paternity.

The members of this line are in a sub-clade of haplogroupR1b1a2, the most common in the Taylor surname project and indicating a probable origin in the British Isles. It appears the subclade is R-L21, thought to be Celtic in origin.

Three of the members have tested positive for the SNP L21 (denoting R1b1a2a1a2c in the 2013 phylogenetic Y-tree), M529 and S145, accompanied by L459 and downstream of P312. More SNP testing is recommended.

Group R1b-06: Haplogroup = R-L21

Haplotype Rarity

Based on the values of the individual markers, the members of this genetic family score, on average, in the Uncommon range. Their haplotypes are among the least common 25%.

Genetic Network

With grateful thanks to McGee Utilities and Fluxus Engineering, we calculated and drew the genetic network diagram below.

Fluxus Network Diagram
Fluxus Network.

Color codes:

This network diagram (cladogram) -- based on the current state of testing -- depicts the inferred genetic relationships among the 17 members of the group.

No two members of the group share the same ySTR haplotype and the genetic distances (number of inferred mutations) are quite large for some members.
 

Reading the Fluxus Network Diagram

The network diagram gives a pictorial representation of how members of this genetic family may be related. It depicts inferred genetic branches of the paternal lineage and may be helpful in documentary research.

Caveats
  1. The inference criterion used to build the diagram is maximum parsimony or "Occam's Razor". This criteria (fewest possible assumptions) may not be the most appropriate in all instances.
  2. The diagram is not proof; it is one interpretation of available geneitc data. Alternative interpretations may be possible.
  3. ySTR data is "noisy"; it contains some unexplained variability. .
Notes on the diagram:

TiP Scores

TiP general

TiP Scores Explained

TiP (for "Time Predictor") is a utility provided by Family Tree DNA. It is accessible to all FTDNA customers with Y-DNA results who have matches listed within the FTDNA reporting windows. It is also available to project administrators for calculating the probabilities that any two project members share a direct paternal ancestor within up to 24 generations.

TiP is superior to most TMRCA calculators. Rather than assume an average mutation rate for all markers compared, TiP uses individual marker mutation frequencies. Because marker mutation rates vary significantly between markers, the TiP scores 

As we use it here, TiP is a truer and simpler measure of genetic distances between individuals than other metrics such as the number of markers in disagreement or a sum of the differences (sometimes called "genetic distance"). TiP boils the complexities down to one number.

The composite TiP score is an index of how closely a member matches the entire group. Generally, the member with the highest score is the central member.

Note:

Unless stated otherwise, TiP probabilities are from TiP version 1 (v1) in effect from August 1, 2012 to December 11, 2012. Another version was in effect from December 12, 2012 to January 17, 2013 and was replaced with version 3 (v3) on January 18, 2013. We are in the process of updating to v3. In the meantime, we've made some observations about how v1 and v3 compare:

This group is the 19th most closely related to R1b-04 with a 50% chance of sharing a c common paternal ancestor within 24 generations.

TiP Relationship Index

We devised a "relationship index", based on TiP scores, using this method:

  1. Record the TiP TMRCA probabilities for 24, 12 and 8 generations past of each pair of group members, based on the highest resolutions comparable. Comparison resolutions are indicated by color: gold for 111 markers, green for 67 markers and blue for 37 markers.
  2. Take the geometric means of the 24, 12 & 8 generation scores for a composite TiP score. (The geometric mean reduces the effects of outliers.)
  3. Subtract the geometric means from 1, multiply the result by 100 and round to the nearest integer.
  4. The final index number represents a hypothetical distance of relationship. Smaller numbers represent more closeness (0 is self). Larger numbers represent more distant relationships, with the maximum being 100.
This yielded the following matrix < < < < <<<<<<<<< <<< <

Haplogroup & SNPs

Seven of the 17 members have tested positive for ySNPs downstream of R-M269, all within the R-L21 subclade; 10 have done no SNP testing. Two have tested positive for FGC18451, suggesting that others in the group may also be positive for it. More SNP testing is recommended for confirmation.

Phylogenetic placement

R-CTS11722 (AKA, R-L1065) is downstream (a subclade) of R-M269. The apparent progression is M269 > P312 > L21 > DF13 > ? > CTS11722/L1065?. > S744 > S764 > FGC18451

Location

The highest present concentrations of the ancestral SNP L21 are in the British Isles and Brittany. S764 seemingly is most frequent n the Scottish lowlands and northern England.

SNP Age

CTS11722 is believed to have formed about 3.6 kya and the MRCA for all CTS11722+ men lived about 1.75 kya. S764 is believed to have formed about 1.75 kya and the MRCA for all  S764+ men lived about 1.25 kya. FGC18451 is believed to have formed about 1.25 kya and the MRCA for all FGC18451+ men to have lived about 500 years ago, within the genealogical time frame.
