Dumha Goirt is based on the Watts font used in the early 19th century. Dumha Goirt was first digitized in 1997 by Michael Everson and originally used the MacGaelic character set on the Macintosh platform, and ISO/IEC 8859-14 on the PC.

The older version of the font was named “Acaill”. In 2011 Dumha Goirt version 3 was released in OpenType format, completely compliant with Unicode encoding and with an extended character set. Dumha Goirt is pronounced [ˈduː ɡɔrʲtʲ]. This is a small village on Acaill where Edward Nangle had the Achill Island Mission which used the Watts type for Bibles and for the Rev. William Neilson’s “An Introduction to the Irish Language”. The town’s name was anglicized as Doogort [ˌduːˈɡɔɹt].
