We could theoretically speculate that the Y tribe might be native to the Dravanian Hinterlands. Y'shtola as well as her sister, Y'mhitra, are natives to Sharlayan, but do seem to hold to the traditional naming conventions. Either the Y tribe is native to Old Sharlayan and came over to help with the colony, or they were living in Eorzea when Colonial Sharlayan was established and assimilated into it.
Could also be wrong and Y'shtola and her sister just became Sharlayans by studying there and becoming citizens the old fashioned way, but its enough of a breadcrumb to build off of.
