My surname is Arvoy and as far as I know it has always been. I wonder, does anyone here recognize this name? It seems as though if my grandfather came to the states and his name became Arvai then there may be two names here?

I am looking for Arvoy from Hunary. My grandfather emigrated to the states in 1906 to Port Huron Michigan. His mother was named elisabeth.

Anyone care to take an educated stab at some possible help in this?
