antoine philippe de marigny

antoine philippe de marigny de mandeville -lrb- 17 july 1721 - 6 nov 1779 -rrb- , chevalier de st. louis , was a french geographer and explorer .
born in mobile in 1722 , he was part of the creole elite of french louisiana .
his family was part of the minor provincial nobility of france , tracing back to pierre philippe de marigny de mandeville , who was ennobled in 1654 .
antoine 's parents were françois philippe de marigny de mandeville , a native of bayeux who arrived in canada in 1709 and louisiana by 1714 , and madeleine le maire , who remarried to the colony 's royal engineer , ignace françois broutin , after her husband 's death .
in 1748 , antoine de marigny married françoise de lisle , thought to be the daughter of guillaume delisle .
they had two children : pierre enguerrand de marigny , and madeleine philippe de marigny .
he also seems to have had at least two children by an enslaved native american woman .
like his -lrb- probable -rrb- father-in-law guillaume de lisle , geographer to the king , antoine was an accomplished cartographer .
he made a detailed map of louisiana in 1763 .
during the tumultuous kerlerec administration , antoine took the side of kerlerec 's commissary-commissioner , vincent de rochemore ; antoine and rochemore were both arrested and sent back to france -lrb- along with the royal colonial treasurer jean baptiste d'estrehan -rrb- .
in france , they continued their dispute with kerlerec and were imprisoned in the bastille for a short time , before eventually prevailing and seeing kerlerec sentenced to exile .
antoine returned to new orleans , where he died in 1779 and was interred at the st. louis cathedral .
antoine 's son , pierre enguerrand de marigny -lrb- also known as pierre `` philippe '' de marigny de mandeville -rrb- , married jeanne marie d'estrehan , daughter of jean baptiste d'estrehan .
they were the parents of bernard de marigny , for whom the famous faubourg marigny neighborhood is named .
