by John Marshall, Royal Naval Biography — Strachan… (1823)
“ The surname of Strachan, which in the successive changes of orthography appears Strathechyn, Strathaquin, Straquhen, and otherwise, is local, there being a parish so called in the north of Scotland. Nisbet affirms, that the district was anciently erected into a county palatine, as he finds a Walterus, Comes Palatinus de Strachan, and considers it the only instance known in the kingdom. The family is traced by authentic documents from a period of high antiquity. ”
