About this Group

This was the second matched group identified by Taylor Family Genes. At eight members, it is one of the largest in the project.

We believe that the common paternal ancestor for this group is James Taylor (1642-1698) who founded one of the most famous and prominent families in America of the 17th, 18th and 19th centuries. It includes, heroes, generals, a president and other leaders and founding fathers of the United States. It is also associated with the Madison, Lee, and Davis families.

We also advise visiting the website of the association for this Taylor family. Its URL is http://freepages.family.rootsweb.ancestry.com/~taylorassoc/

The12th US President Zachary Taylor, a hero of the Mexican-American War, was also a member of this family. (See tree by Richard Lewis Taylor.) Zachary Taylor has no known living direct filial descendants; the two sons of his only known son died in childhood. However, Zachary shared his Y-chromosome with many brothers and cousins.

James Taylor bought land parcels in the hundreds of acres from December 1675 onward and may have done so before. (Earlier records have been lost.) He married a woman reported  to be named Frances Walker about 1667 in New Kent Co., Virginia and Mary Gregory in 1682.  His descendants went on to become one of the most prominent families in colonial America and the United States. Their statuses and accomplishments produced a rich documentary record.

James Taylor's Origins

James' origins, however, are murky -- despite some sensational claims. His birth date and place and parents are essentially unknown and no records have been found to substantiate the statements of an illustrious heritage. Many of these claims are taken from Mary Taylor Brewer's "From Log Cabin to the White House". Ms. Brewer cited few sources and may have taken unwarranted leaps in drawing her connections.

A more authoritative source is Ann K. Blomquist's online publication, "Tate, Taylor, and Southern Families". Ms. Blomquist is careful to distinguish between the reported stories and the documented facts. (She lists more than 5,000 Taylors, of many families, in her database.)

The best hope for finding James Taylor's origins may lie in DNA-matching. A match with a present Englishman may indicate James Taylor's place of origin and possibly more abut his family.

Other claims

Rowland Taylor (1510-1555) is the earliest claimed ancestor of one member of this group. (See tree by Henry Anderson Taylor.) Born in Northumberland, Rowland was rector of a small parish in Hadley when he was  burned at the stake by order of "Bloody" Queen Mary. He is viewed by Protestants as one of the great Christian martyrs.

  Also see this tree, emphasizing female descendancy from Thomas Taylor (1573-1656) & Margaret Swinderby/Swinderly. Further, we recommend reading Nathaniel Taylor's work here; see especially "Bogus Origins".

Group R1b-02: 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 37-marker genetic network diagram below.

Fluxus network diagram
Fluxus Network

The above diagram shows three exact matches at 37 markers and two branches. One branch has one mutation in DYS449 and another branch has mutations in CDY and DYS576 (two highly volatile markers.)

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 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.


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:

Genetic distance from other groups

The most closely-related other groups in Taylor Family Genes are

This group is the 12th most closely related to R1b-04 with a 27% chance of sharing a common paternal ancestor.

Haplogroup & SNPs

One member of the group has tested positive for the SNP known as L47, definitive of haplogroup R1b1a1a2a1a1c2b1. Additional SNP testing is suggested.

Phylogenetic placement

R-L47 is downstream (a subclade) of R-M269. The apparent progression is M269 > U106 > S263 > S499 > L48 > L47. Known subclades of L47 include  L44, Z159, Z9, & Z30 (each with multiple subclades).


The highest present concentrations of the ancestral SNP U106 (a.k.a S21) are on the te North Sea coasts , the Netherlands and northwest Germany. Its very strong presence in England may be due to the Anglo-Saxon migrations of the 5th century.


L47 is believed to have formed about 4.8 kya and the MRCA for all L47+ men lived about 4.5 kya. (Closeness of the two estimated dates suggests rapid division into the various subclades, perhaps a result of population and territorial expansion.)
