circa 1300, sioun, "a shoot or twig," especially one for grafting, also figurative
from Old French ciun ‘shoot, twig’
The meaning "an heir, child, a descendant" in English is from mid-14c., a figurative use. The proper spelling would be sion; the -c- in the French word, and hence in the English, is unetymological.
[Etymonline]
ciun is of uncertain origin
the etymology of scion/ciun is not to be confused with sion
