Notes - "Due to the proximity of their lands to the Saxon kingdom of Mercia, the family descended from Llyddoca ap Tudor Trevor had established amicable relations with their neighbor to the east; it is believed the first Rhys Sais became fluent in the Saxon language and served the Earl of Mercia as latimer or interpretor. Thus his nickname "Rhys the Englishman". Apparently his son Tudor and grandson Bleddyn served in the same capacity for the Norman Marcher Lords, the Earls of Montgomery. It was during the lifetime of the first Rhys Sais that the majority of his lands (all but Nanheudwy which, among his holdings, lay the furthest west) were detached from Powys to become a part of the Norman shire Salop (now Shropshire)."
