Danes and Britons and me

23andMe, a company that furnishes DNA analysis, advertises that it can tell me if I am related to Danes who were murdered in the St. Brice's day massacre.  According to what I have seen, someone informed King Aethelred II of England that Danish immigrants were plotting to kill him.  So he ordered his troops to kill all Danes.  The massacre of Danes took place in 1002.

I have read that names such as "Kirby" and "Derby", ending in "by" come from Danish and Danish settlers who held a part of Britain sometimes called "Danegeld".  The word refers to a tribute or protection money collected to pacify Danish raiders and bribe them not to attack parts of Britain.  I had read previously that "Danegeld" referred to an area of Britain where Danish money was accepted but the Duckduckgo browser just gave me a different story.

Duckduckgo says that homo sapiens goes back 300,000 years.  I don't feel any responsibility for the share of them that were my ancestors.
