meh! Either create new tags for Gallo, Angevin etc or reflect cultural differences.
Gallo was one of the two languages used by the court of the Dukes. Gallo is a oil language, and therefore a romance language. But it does not comfortably fit in with the 'Frankish' culture or variants of language - it is a distinct language. cf

Gallo is a cross-over point. And while you could fit it in with the Franks if you were truly desperate, then you'd also have to change the culture of the Dukes of Brittany because otherwise they'd be a totally different culture from their people; which is definitely not true
Contemporary writers (eg Chronique de St.Denis from C13th refers to the inhabitants of Britanny being those who spoke the ancient language and those who spoke that language mixed with Latin; which isn't true re.origins of Gallo - but does imply that Gallo was not considered to be 'French') referred to a 'double Brittany' - a Brittany of two languages but united; much as Scotland was Pictish, Scottish and Welsh but 'united' under one crown. With France though, I don't think there are enough tags to represent the regional languages (which are in no way 'patois' as research into them is showing).
re. Devon. Earl seems to rely mainly on place names for most of his reading of Devon's linguistic status - this is at best flawed when 'cott' and 'worthy' (common in North Devon) could either come from Anglo-Saxon 'cot' and 'worthig' or Celtic 'coet' and 'wartha'. 64 placenames in Devon retain the celtic 'cwm' in Domesday, as opposed to a handful in each of the other counties in England (exceptions being Somerset with 30 something and Dorset with around 20). Eventually, there will be a revision of how we view the west-country Celts because the evidence on the ground (eg styles of farming matching Celtic norms not Anglo-Saxon) is starting to be matched with the linguistic evidence of people who know Celtic as well as Anglo-Saxon (eg local pronunciation of names matching more closely a Celtic origin for a place name than an Anglo-Saxon one), but it is contentious at the moment. I'm quite happy to mod this in myself; this project keeps being derailed by petty things, and my evidence on Celtic is likely to be viewed as biased
