I have seen Mervine spelled: Merwein, Meerwein, Mehrwein, Marevine, Marvine, etc. You will find the name in Ger- many. You may also find it spelled Murvine. My Mervines lived in sections of Germantown and Roxborough Twp. in Phila. Co. that were predominately of German descent. One son of Philip, Jacob, resided in Northampton Co. from the 1790's and later. Perhaps you are descended thru him.
