Howe-Orme instruments were made by the Elias Howe Company of Boston, MA. The Howe company was founded by Elias Howe (1820 - 1895) but the Howe-Orme instruments appeared after the death of Elias, when his sons William & Edward Howe had taken over the company. The Orme part of the brand name belonged to George Orme of Ontario who (along with James Black) held a patent for a longitudinal belly ridge for guitars - this was used on the Howe-Orme instruments which were a range of acoustic guitars, mandolins, mandolas and banjos.
