Dear Prof. Chambers,
As imina is also written as "忌み名," teaching their own imina means
being dominated. The word "知る" also means "to dominate." Therefore,
when entering into a master-servant relationship, one teaches the
person who will be the master one's name. The reason why Yoshikiyo's
imina appears in the story is probably that he is a servant of
Hikaru Genji.
A woman never teaches her imina to anyone other than her husband.
For example, the Kamakura shogunate issued kudashibumi 下文, which is
a certificate that proves a fief of gokenin 御家人. But there is no
kudashibumi to be issued for female lords, which at that period,
were not rare. Because the format of kudashibumi was just for the
servent of Shogun, and because women did not have a master-servant
relationship with the general. For female lords, the shogunate
issued the certificates in the other format.
The reason why male imina were recorded is probably that they had
many opportunities to teach their imina in public. For instance, in
the case of aristocrats, when they are appointed in the court, they
are issued a document called iki 位記. At that time, they had to
inform the court of their imina in order to be written their imina
in the iki. The records of the appointment are still partially
preserved today, so we can find out their imina from those records.
In other cases, the diary of noblemen, which is not private records
but public ones, may reveal the imina of people serving in the
court. Also we can find imina out of family trees.
