Ladies, do you like your surname?

Here’s another little bit of useless information that I found interesting.  It is the loss of surnames.  You probably don’t ever think about this, but it was in an article sent to me years ago by a fellow genealogy friend and I thought it was worth passing on.

Your surname may not last through time.

Only 20% of the surnames in use exist after 13 generations.  Ninety percent of all family names from the 1700s are now exterminated.  Each time two persons married a surname was lost.  This happened more often when families had many children.  In 1874, the Social Security Dept. had 1,286,556 different surnames on file, of which 448,663 were single occurrences.  I wonder what that number is today.
