I am hoping that I have the info you are searching.I looked for a Della Turner on the 1900 IN census and only one matched up age wise, as follows:
1900 Hendricks Co., IN(Hendricks is a neighboring county) Lucy Turnerheadb. 4/185747widowedb. INparents b. KY Ettadaub. 12/188118singleb. INfather b. KYmother b. IN Freddiesonb. 8/188415b. IN(all births same for children) Aultmansonb. 2/188713 Delladaub. 11/188910b. IN Orda E.sonb. 10/18928b. IN
So I went looking for a marriage record for Lucy and Turner in Hendricks county and found: Turner Andrew Lucy RaineyFeb 22 1869 7 148
I then checked the 1880 census Hendricks Co., IN and found: Andy Turner36b. KYparents b. KY Lucy29wifeb. INparents b. KY John B.11 sonb. IN William8sonb. IN Emma6daub. IN Laura3daub. IN Minnie9/12daub. IN
1870 Hendricks Co., IN Andrew Turner22b. KY Lucinda17b. Ky John3/12b. IN
