What's that bit at the bottom where it says "pour Mamere Justine _____"? I think it means for grandmother Justine____? Maybe the grandmother made sure the baby was baptized, since the father was unknown and the baby was baptized the same day she was born, who else would do it?
Dit and Ditte followed by a noun/adjective means it's a nickname. My ancestry has Abraham Martin dit L'Ecossais (the Scotsman) and Jean-Baptiste Tetreau dit Ducharme (the charmer), I have seen baptismal records with ditte and that would just represent the female version of the nickname. Looking at my French-English dictionary I find that laconique means terse, laconisme means tersely, why wouldn't laconire mean the terse one?
It does look like pere inconnu, the godmother is Marie-Catherine Antoinette, fille (single) and the godfather is Jean-Francois Thery/Theri (two different spellings in the copy) The birth is 14 Oct., 1790.
