Nancy's parents may be this couple, but my inability to find them or Nancy in the 1850 and 1860 censuses means the connection has not been proven:
Father:  John B. MALONEY / MALLONEE
Mother:  Elizabeth EADES

— said to have had these children:
5.  Margaret "Madge" Everett BROWN, b. 11 Apr 1881, Georgetown, Vermilion Co., IL; d. 11 Feb 1966, Los Angeles Co., CA; m. William Anderson MISKIMEN (1882->1930)
6.  Charles BROWN

Several other members of this BROWN family moved to Louisiana, so it's not unreasonable for them to have been there.
