About this Group

This was the first genetic family identified in the project.

The I1 haplogroup — which occurs in its highest frequency in Scandinavia — accounts for 10% of the Taylor surname; most Taylors fall into R1b1. Its prevalence in the name is, perhaps, attributable to Danish settlements in England during the 9th & 10th centuries.

There is clear documentation that Robert TAYLOR (1688 Old Rappahannock VA -1758 Edgecombe NC) is the son of Lorana Hudson Taylor. Our current best information is that Robert’s father and the husband of Lorana Hudson Taylor was born in 1662/3 in Old Rappahannock, VA – and died in 1693 Essex, VA . The father of this unnamed husband of Lurana may have been Robert Taylor (1625 – 1662) who married Margaret Welsh and died before his son was born. His 1662 will mentions an unborn child.  

Much of what we know about this line comes from Josh Taylor, a Taylor Family Genes co-administrator. His story is a common one in genetic genealogy.

 

NPE?

Note that several members of this group have the Winchester surname. We believe that there may have been a NPE (not-the-parent-expected) sometime in the ancient past. If and when or where this happened is not known; research continues.

Genetic Network

With grateful thanks to McGee Utilities and Fluxus Engineering, we calculated the 37-marker genetic network diagram 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.

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. .

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:

Haplogroup & SNPs

Almost half of the group's members have tested positive for the SNP known as M253, definitive of haplogroup I1. More refined SNP testing is suggested.

Phylogenetic placement

I-M253 is downstream (a subclade) of I-M170. The apparent progression is M170 > M253. Known subclades of include DF29, M27, M227, M72, S244, & S247.

Location

The highest present concentrations of I-M253 are in Scandinavia and northern Germany. Its significant presence in the British Isles may reflect Danish and Norse settlements of the 9th to 11th centuries.

SNP Age

M253 is believed to have formed about 27.5 kya and the MRCA for all M253+ men lived about 4.7 kya. (Comment: The MRCA time is roughly coincident with the explosion of R-M269 into sub-haplogroups.)
