About this Group

Members are invited to submit information about this genetic family.

This genetic family shares two primary surnames, Taylor and Cothern or Cothron, plus a couple of others. We believe a NPE or surname discontinuity occurred long ago to split this genetic family into separate Taylor and Cothern branches tracing back to Emanuel County, Georgia.


Y-DNA Values

See http://www.familytreedna.com/public/taylorfamilygenes/default.aspx?section=yresults.

This genetic family appears to have an uncommon, distinctive haplotype and higher than usual propensity for mutations.

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:
