About this Group

The members of this line are in haplogroup R1b1a2, the most common in the Taylor surname project and indicating a probable origin in the British Isles.

Group R1b-19: Haplogroup = R1b1a2

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 the genetic network diagrams below.

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.

  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. .

TiP Scores

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.


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:
