I think I found her with her parents in the 1900 census Harrison Co., IN:
James W. Carroll b. 10/185346Mrd 16yrs.b. INparents b. IN Lou A.b. 6/1863369children/8livingb. INparents b. IN Frank J.b. 12/188415 Ida Myrtleb. 4/188614 Nellie E.b. 12/188811 Essayb. 3/189010 Lilly G.b. 11/18918 Evab. 9/18936 Williamb. 8/18954 Minnie R.b. 8/18999/12 John W.b. 8/18999/12(twins)
Another suggestion...since you know her death date, you may want to get her death certificate - they many times had the parents' names on them.
I wasn't able to find them in the 1910 census, but James and Eva are in the Tippecanoe Co., 1920 and 1930 census records.
