If you believe that advice and relatives are inseparable, the etymology of "kindred" will prove you right. "Kindred" comes from a combination of "kin" and the Old English word ræden ("condition"), which itself comes from the verb rædan, meaning "to advise." "Kindred" entered English as a noun first, in the 12th century. That noun, which can refer to a group of related individuals or to one's own relatives, gave rise to the adjective "kindred" in the 14th century.
