Oxford Ancestors has replied to my query about how they determine a high
probability of a Viking background for Y-Chromosome tests of people whose
ancestors came from Britain.

>Dear Mr Page,

>Thank you for your email on 25/3/02 regarding our Y-Line service. I am
>sorry but Prof Sykes is now away on sabbatical, writing his next
>book. Your email has therefore been passed to me for comment.

>In reply to your queries:
>
>1) To indicate if a person is likely to be of Norse origin we look for
>an 11 for marker DYS 392 which you possess.
>
>If a person is not 11 at this position then it is highly unlikely that
>they are of Viking origin (although this doesn't mean it is
>absolutely impossible) and that they are more likely, if they live in
>Britain, to be of Celtic or Anglo-Saxon origin . Our work is based on
>the paper by Helgason which is detailed on our website. More details
>of this research may be found in this paper. Unfortunately due to
>copyright issues we are unable to send you a copy of this paper,
>however it may be accessed on www.journalsuchicago.edu, with the first
>author being Helgason.
>
>In Britain these 'Vikings' live predominantly in the north,
>particularly in Scotland, the Scottish Islands and the north of
>Ireland. If you are interested in the Vikings you may find
>www.Pastforward.co.uk/Vikings an interesting site to visit.

>Oxford Ancestors expect to have a database in place by summer so that

>to both, at http://ystr.charite.de * (see below).

>2) I am sorry but I do not know about the pattern found mostly in
>Norway and Iceland. However, there is a group who are involved in a
>study into Icelandic genealogy who are aiming to genotype the whole
>population of Iceland and they may be more able to answer your

>*With this particular database, conversion of two of the Y-Line
>signature numbers is necessary before comparison.

>For DYS389i - you need to add 3 to the number of your allele as
>reported by Oxford Ancestors. So, if you are a 9 for DYS389i, input
>this as a 12.
>
>For DYS389ii - you need to add together the two numbers reported by
>Oxford Ancestors for markers DYS389i and DYS389ii and then add 3
>again. So if you were a 10 for DYS389i and a 16 for DYS389ii, to use
>the ystr.charite.de database you would input 13 for DYS389i (10+3) and
>29 for DYS389ii (10 + 16 + 3).
>
>These conversions are necessary because Oxford Ancestors actually
>reports the number of repeats for the DYS389i and DYS389ii markers
>individually. The database requires input at DYS389ii that is
>actually the total of DYS389i plus DYS389ii, as this is the result
>generated by the DNA sequencing equipment in the laboratory.
