Here are two birth record from St. Martin Parish, Louisiana. The records only include the mother's name, which could mean that the father was white and the mother black or some other "problematic" relationship according to the laws of the time. But, what exactly does c.l. really mean?
AUBRY, Marie Alice c.l. (Celeste AUBRY, c.l. ) b. 9 Aug. 1862 (SM Ch.: v. 10, # 1213)
AUBRY, Gabriel c.l. (Celeste AUBRY) b. 16 Oct. 1864 (SM Ch.: v. 10, #1312)
