I believe you're our first "N" -- you must be rare. In fact, I don't even see
"N" on the map of world migrations at

There's not a web site for the Cambridge Reference Sequence per se. There is
a database with results reported from the literature at

http://shelob.bioanth.cam.ac.uk/mtDNA/

You would check the database for listings with your "haplotype" -- that is,
your pattern of differences from the Cambridge Reference Sequence. Your
Oxford Ancestors report shows your sequence for 400 base pairs, starting at
position 16001, with your differences in red. You need to count off the
positions and write out your haplotype something like this:

16145[A] 16176[A] 16223[T] 16390[A]

That's what I got when trying to read your sequence in the e-mail message,
but you should double check it on your colored report.

However, you won't find any exact matches for your sequence in the
Concordance. This is not unusual -- just about every time a researcher
studies a new group of subjects, novel haplotypes are found!

I suspect the RG database will be limited to people who have their test done
by them. They cover somewhat different sections of the database. We have
talked from time to time about a public database, where anyone could enter
their results, but random matches wouldn't be very helpful anyway. However,
if you have a hypothesis about mtDNA relatives of your most distant
matrilineal ancestor, mtDNA tests could be very informative in supporting or
ruling out your hypothesis.
