I do know of an Etta WISE born 1865 that married a Thomas H. CROMER and they had a child named Ethel June CROMER born 1892. That's the only Etta that I know of tied to this family.
His brother, William Harrison CROMER (1859-1937) married Elizabeth A. GROSVENOR (about 1857-after 1937) and they moved to Manistee, MI. They had children named Floyd, Grace, Elizabeth and Clyde all born about 1892-1890.
The CROMERS were originally from Miami County, OH but moved, later, to Clinton TWP, Shelby County, OH and the GROSVENORS were from Shelby County, OH.
Sorry, I could not give you more information....
