family_name_ - Family name for font

This is the family name of the font. The name is case insensitive and may include a foundry name. The family name may optionally also include a foundry name, e.g. Helvetius [Cronyx]. If the family is available from more than one foundry and the foundry is not specified, an arbitrary foundry is chosen. If the family is not available a family will be set using the font matching algorithm
