Usually when I am talking about Y I am talking about Y-DNA, as in the male DNA passed from father to son. But today I am discussing about a different Y. I have been seeing a great deal of deaths in this location in Ancestry.com trees and elsewhere. So far not a single one of them actually died in this location. This isn't surprising since its not a very populous place. You can see the wikipedia page for this location for population over the years. Y, Somme, Picardie, France is a very small place indeed!
This location is an error, likely introduced by the suggestions for locations and incorrectly merged locations. The person entering in the data wants to say "Yes" and enters "Y" and somewhere along the way it becomes "Y, Somme, Picardie, France". Once one person accepts it on Ancestry.com it becomes suggested to other "Connections" for people. You can see a more detailed post by another researcher here.
