<Brigid> - AStG Report 1716 - Saint Brigid was venerated throughout the Gaelic world. Apnd-H Doc Brigid is a feminine given name documentable as a Saint's name from Catholic Encyclopedia Online. http://www.newadvent.org/cathen/02784b.htm, which references her relics being (re)discovered and venerated in 1185 as well as her inclusion in the Stowe Missal of the 8th or 9th century. Spellings of the name from the Annals Index include forms with -t- and -d-: sancte Brigide/sancte Brigite. It also includes a form with -t: S. Brighit. These suggest an early Brigid.
