In the Middle Ages sometimes two
brothers or other near relatives had exactly the same name. Genealogists have
sometimes run into a wall in attempting to determine which of two
thirteenth-century Fulk fitz Wains was really the ancestor they sought, or which
Robert Helias de Say, or which John le Strange. Then there was John Matravers,
who by different wives had sons named John, and the younger of those had two
sons named John.
In France such a problem was
usually avoided. A younger brother of Jehan (John) was sometimes named Jehannot
(little John), and sometimes a second Guillaume (William) was named Guillot
The duplication of names
occasionally extended to girls. The will of a sixteenth-century Englishman,
Thomas Reade, refers to "my daughter Katheryn the younger" and
"my eldest daughter Katheryn."
