On the 1900 Census in Monett, Barry County, Missouri were William F Key (b: MO 1861), Lillie M Key (b; MO 1863), Eudora Key (b: MO 1885), Pearl N Key (b: MO 1889), Ralph W Key (b: MO 1890), and Edna O Key (b: MO 1896).
The three older children are actually the children of Lillie's first husband James M Lawson (b: AR 1857).
Lillie (Lila May) Gray married James M Lawson on 17 Sep 1881 in Lawrence County, MO.
Lillie Lawson married William Key 3 Nov 1891 in Lawrence County, MO.
After 1900 I can't find any of the people above.
Any help in locating them will be greatly appreciated.
