Looking for the parents of Mary Elizabeth RONGEY.

Antoine L. Boyer, b. ca 1818 in MO, is listed in the 1850, 1870, and 1880 censuses in Union Twp, Washington Co, MO. His wife is variously Mary L. and Elizabeth, b. ca 1821 in MO.

They had ten children born between 1839 and 1865: Zoa, Julia Ann, Ferdinand, Mary, Napoleon, James, Olive, Lucinda, John, Julius.

I have death certificates for several of their children that list their mother's name as Mary/Elizabeth/Lizzie Rongey/Rangey/Rengia, all corruptions of Rangé.

A couple of undocumented internet/Ancestry trees list an Elizabeth Rongey, b. 1821, as a daughter of Lambert Ranger. But Lambert's will, made in Washington County, only names a few of his children: Henry Rongey, Louis Marshall Rongey, and Margaret Julie Bequette.

Does anyone have any sources that prove the link between Mary Elizabeth RONGEY and Lambert RANGER? Or another father?
