Do you have your grandmother's complete birth date? If so, and if she is deceased and appears in the Social Security Death Index, you can write to the SSA for a copy of her SS5 application for social security. This document will give both parents' full names (including maiden surname for mother).
In the meantime, in the 1930 census, John W. MEYER and Lena's household includes a sister-in-law, Anna J. Apple, single, born PA, parent born GER. This suggests that Lena's maiden name might be Apple (or some spelling variant thereof). (Source: 1930 United States Federal Census >

Going back to the 1925 IA State Census, Lena Meyer's parents are listed as John
Appel [born GER, deceased] and Christina
Marquart (born GER, deceased), who were married in PA.
