Many “old” British surnames have been disappearing in recent years; the names which have been used for generations are being lost. Many scientists think the reason maybe the following. In modern times people have become increasingly embarrassed to hold “funny” and unusual names that may make other people laugh.
Some last names like: Cock, Daft, Death, Smellie, Gotobed, Shufflebottom, Willy, Nutters, Piggs and Jelly have declined seriously in the past century or so. We imagine that these people have changed their names to something innocuous.
