The Seven Valleys basin was settled by forty families of the German Lutheran and Reformed faiths. They originated in the Hunsruck Mountains of the Rhineland Palatinate and arrived in this valley of the Codorus during the early fall of 1738. The lush meadows and gently rolling hills here reminded them of their homeland, even to the presence of seven valleys in the vicinity, and they called it Das Siebenthal, which in German means Seven Valleys.
By 1752 these religious hardworking farmers had organized churches and parochial schools, and holding fast to their German heritage, worshipped God and taught their children in the Pfalzer dialect of the German language for nearly 150 years.
