No, it means she was a minor. This is from the library's site:
This category of court proceedings relates to the emancipation of minors, rather than of slaves. (See the section on Slavery, Free People of Color, and Freedmen for slave emancipations.) In Louisiana minors above the age of eighteen but not yet legally adults sometimes came into the possession of property, often through succession. In order for minors to be able to handle their own property, state law provided for judicial emancipation . Records of emancipation proceedings usually include the names of the minor and parent(s), the age and/or date of birth of the minor, and some statement of the reasons for requesting emancipation. The earliest emancipation records appear to have been filed in the Parish Court [mf VCP], but some also exist in the files of the First Judicial District Court [mf VMA]. After 1846 emancipations were filed in the Second District Court [mf VSB] and, after 1880, in Docket 1 of Civil District Court [mf VT].
