Googlegangers
Years ago, I read that “Kirby” is the 511th most common name in the US. I mean last names, family names, not counting cartoon characters named Kirby. I learned in the movie “*6888” that the US Army was swamped with letters to and from servicemen in the beginning of World War II. Something like SEVEN warehouses of letters were filled with letters not delivered to the intended recipients. The movie “6888” tells the story of the terrific backlog which was entrusted to the 6888 battalion of Black female soldiers who finally straightened out the mess, which included mail to 7500 men who were all named “John Smith”.
In German folklore, there is a type of character called a doppelganger who is your exact double and whose activities are not always kind and supportive. Somebody invented the term “Googleganger” to mean people with the same name. That situation can be quite a bother for both people in this day of digital communication, with frequent invitations to “create an account”.
