Susie & Dave, I believe you will find Lillian MAUGER on the 1880 Census as Lillie (indexed as MANGER on LDS FamilySearch.com) in Columbus, Franklin Co., OH. I don't have access to the census page image but it appears she is living in an apartment house or boarding house since there are fourteen people residing there. The index says pg. 302B, entry 2585.
Here's the whole group:
Lawrence, Edward - - M 30 Connecticut McDonald, William - - M 21 Ohio, Ellis, Henry - - M 30 Ohio Brelsford, Lewis - - M 22 Ohio Livingston, Laura - - F 30 Ohio
*Manger, Lillie - - F 30 Ohio
Osgood, Wentworth - - M 35 Ohio Rev. Miller - - M 48 Ohio Miller, Martha - - F40 Ohio Henderson, May - - F 28 Indiana Rodgers, Louisa - - F40 Kentucky Shaw, Thos. G. - - M 58 Massachusetts Shaw, M. G. - - F 48 New Jersey Shaw, Charles D. - - M 16 Kentucky
I am enjoying and learning from your exchange; keep it up.
