About us

The standard FTDNA reports for STRs and SNPs can be seen under the DNA Results tab at top left.

These phylogenetic trees show the 'relatedness' of the test results.
The length of the branches indicate the relative TMRCA.

Note that these first 2 graphs are now slightly out of date with regard to the M269 (R1b1a2) subset.

All members, with groups compressed.

This shows the relationships between the groups.

All members, expanded.

M269 (R1b1a2) subset...
Tests with 37 or more markers were recently analyzed and grouped to maximize parsimony.





R1a subset.

I subset.


For the technically minded...

I used to generate the TMRCA data,
using the Hybrid mutation model, 50% probability, and "MacDonald" mutation rates.
The resulting PHYLIP data text was then fed into the Kitsch program.
The resulting Kitsch output was then graphed, massaged and labelled using Mega5.0.
This link was helpful at first -
If any of you know of a better or easier way to graph the PHYLIP data, please email me.

For this table I used data from...
Population per Country -
Top 10 Bruce frequency by Country -
The frequency for the 'rest of the world' is guestimated at 0.5 per million.

Our current project size (~130 members) represents roughly 1 per 1000 of the global Bruce population.
It is interesting that the frequency is higher in some of the colonial countries than in the UK.
Seems that Monty Python was correct about Bruce in Australia!
