The records of Marans of that time are in a bad shape. Marriages from Aug 1649 to May 1661 are missing, so probably all three sisters fall in this hole. Baptisms of the 1620's and 1630's are there, but they are not well ordered and there is no table: if somebody as the courage to read 300 pages of barely legible handwriting, then maybe the baptisms of Louise and Michelle with the same parents can be found.
Fichier origine gives a precise date for the marriage of Michelle: 10 Dec 1652. Any idea where this date comes from?
Also in fichier origine, there is an error on the baptism of Michelle's first son, Jacques Cardinal: it is stated as 23 Feb 1656, but at this date one finds the baptism of another son, Pierre, who probably died young. According to his age at census, Jacques is rather born in 1654 - but baptisms from May 1639 to Dec 1654 are missing.
