Regarding the FS profile for Flore Use', maybe it's her. There is a death record for "Alce Richard" in 1888 that might be for her husband. I did notice in one of the books (1908 I believe) a marriage record for one of their children showed Alcee was deceased by then.
So she could have remarried and had more children. However I couldn't find any records for a Serrette-Use couple (or several variations of those names) on the CD, neither marriage or children. Maybe they moved out of the area?
Here are a couple of other records from the Hebert SWLR CD that might be relevant to this family:
Another child: RICHARD, Mary Aidy (Alce & Cloridia USEY) b. 3 May 1888 (Carencro Ch.: v. 2, p. 107)
RICHARD, Alce d. 22 Dec. 1888 at age 27 yrs. (BB Ch.: v. 2, p. 98)
