I recently came across this:

From http://www.electricscotland.com/fami...2002/celts.htm

Paragraph 7:

"Because of the paucity of written records, the scope of Celtic settlement
across Europe has not been easy to establish. One feature already mentioned that
is strongly associated with Celtic blood lines is red hair; a great majority of
people in the world who have red hair will be found to have a Celtic ancestor.
But that feature is not uniquely associated with the Celts, so the spread of
Celtic people in such areas as present-day Germany and Scandinavia has not been
accepted by all authorities. During World War II, a discovery was made that only
recently has received meticulous research. A couple of doctors in medical
centers in England noticed that there was a feature of Scots and Welsh soldiers
wounded in battle that was not present with English, Germans, and other
nationalities. The former frequently had a big toe (or great toe) that was the
same length as the next toe; all others had great toes markedly longer. They
marked that down for research after the war ended, but it was only a few years
ago that definitive research was done that has led to a remarkable discovery.
They found that there were burial sites across Britain where the skeletons were
completely of one ethnic group, such as Celtic burial sites on islands along the
Scottish northwest coast, and pre-Celtic burial sites in southern England.
Results from studies of those burial sites showed that to a 95 probability
Celtic remains had a big toe the same length as, or shorter than, the next toe,
while pre-Celtic remains had a big toe longer than the one next to it. That
study was expanded to cover burial sites in other parts of Europe and Asia, with
the same results. Because the so-called Celtic toe can disappear after many
generations of intermarriage, it is not a necessary condition to having a Celtic
ancestor, but it is a sufficient one: if a person has the Celtic toe, he or she
is almost certain to be of Celtic descent."

So, gentlemen, pull off those brogues.
