Lampl means lamb herder and as far as I know is of Jewish Austrian origin.
Recorded in over forty spelling forms from Lambert, Lambard and Limprecht, to Lambrich, Lambertini and Lemmens, this surname is almost certainly of very early German origins. As a surname it started life in the 12th century, but the derivation is from a pre 5th century personal name. (http://www.surnamedb.com/Surname/Lampl#ixzz5fbhGMZjt)''
