The etymology of the first part of the name is ''Gunfridr's farm'', a Scandinavian farmer who probably settled in the 10th century. The Orcher suffix comes from the name of the first
seigneurs of the village, now corrupted to Orcher, but originally
Aurichier (
alor = alder and
kjarr / ker = marsh. Cf.
Ellerker, Yorkshire), that took themselves in turn their name from the same place, where the chateau is located. The commune was created and recorded in 1251 with the merger of the two parishes of Gonfreville and Gournay. A
priory had stood here since 1024 but long before that,
Bronze Age people had been here, witnessed by the tools unearthed during the 19th century and the name Gournay is a Celtic archetype
*Gornako, connected with a wet place. ==Population==
