10: Brighid of the Black lion - New Name
Submitter desires a feminine name.
Sound (Blacklion) most important.
The name was originally submitted as Brighid of Blacklion. The byname was changed at kingdom to better match the available documentation.
Brighid is found in OC&M s.n. Brigit; the entry mentions that there were 15 saints of this name, including Saint Brigit of Kildare. According to precedent (Brygyt d'Arcy of Glen Meara, 06/2003 R-Trimaris), the submitted spelling is the Early Modern Gaelic (c. 1200 to c. 1700) form of the name, and is registerable as a saint's name. Commenters noted that this name (or something very like it) was used in English: Talan Gwynek's "Late Sixteenth Century English Given Names" (http://heraldry.sca.org/heraldry/laurel/names/eng16/eng16alpha.html) has two instances of Bridget.
of the Black lion is a constructed inn sign-based surname based on Gretchen Beck: "Inn, Shop, or House names found in imprints from the EEBO database, 1473-1600" (http://www.contrib.andrew.cmu.edu/~grm/sign-of-the.html). Under the category of 'Color + Beast', examples include signe (or sygne) of the Red lion and signe (or sygne) of the Black beare. R&W briefly discusses sign names on p. xvi under 'Local Surnames', mentioning atte Lamb and atte Raven as examples; a dated example is found s.n. Bell: John atte Belle 1332.
A combination of English and Gaelic is a step from period practice, but registerable (Ian MacHenrik, 10/99).
