It is French, and apparently means 'rocky water'.

I believe it is french

"Eau" is French, meaning water. But gallie is not. Are you sure about the spelling?

Looks to me like french. Eau is water but I do not know gallie.

1) ""Authorities are agreed that the eau is French for "water", but they differ as to the gallie. Some say it is french for "bitter" (like gall); other that it is an Indian word for "rocky"."

Gauley. This native American name is found also in many parts of the world. It is the same expression seen as the final in such names as Eaugallie, Ocala, Oghallah, etc. The names Gaul, Galilee, and Wales all have the same remote origin, doubtless, as this American word. The most remote form of the original expression is seen in the Hebrew of the Edenic river name, De-Kau li, the Biblical Hiddekel, the Oriental Tegari or Tigris."

In French, Eau Gallie means "rocky water".

"Oh, golly!" is an English expression of mild shock. :)
