The “group shootings” marriages.

In the 18th century, weddings were often celebrated at the beginning of the year (January and February), sometimes at the beginning of summer.
It is not uncommon for the ceremonies to be performed "in group shooting", for example six weddings at the same time on February 7, 1736 in La Rochette. Right page 2nd paragraph
There are also many double marriages, two sisters marrying during the same ceremony two different men, a brother and a sister marrying a sister and a brother, for example Jeanne Rasse married in Meursanges on March 2, 1734 Claude Prost (these are direct ancestors of Emile Bouzereau) and his sister Simone marries Luc Boulée during the same ceremony. Right page 1st paragraph
For example, the two brothers Fiacre and Pierre Pallegoix married in Beaune parish of Sainte-Madeleine on February 12, 1697 the two sisters Pierrette and Jacquette Lombois. Left page 2nd paragraph
Some surnames are so widespread that we have found a double marriage between brothers and sisters of the same name: on January 16, 1720, the marriage of Claude Bailly and his sister Claudine (children of Jean Bailly and Claudine Leflaive) was celebrated with Denise Bailly and his brother Claude (children of Claude Bailly and Françoise Bitouzet). Left page 2nd paragraph
And even a triple marriage on January 23, 1745 in Chevigny-en-Valière:
      - Jean Simard marries Marguerite Dominot,
      - Jean Simard marries Marie Simard,
      - Claude Dominot marries Françoise Guilleminot.

• The two Johns are just namesakes.
  
• Claude and Marguerite are brother and sister.
• Jean (from Marguerite) and Marie (from Jean) are brother and sister.

Jean Simard and Marguerite Dominot are ancestors of Jeanne Marie Niquet, our great-grandmother, the mother of Emile Bouzereau, our common grandfather to Simone and me. left page

From gardeners to winegrowers.

Antoine Coignet was a gardener with Monsieur Morel (or Morelle) in Saint-Maur-des-Fossés - just like his father Claude was - when he married in 1687. Then he found himself, I don't know how, in Meursanges - where he died in 1724 - gardener at the Laborde castle.
His daughter Marie Anne, born in Saint-Maur-des-Fossés, married in Meursanges with Denis Coppenet who was also a gardener at the Laborde castle.
Their son Guy becomes a gardener at the orangery of the Laborde castle. In 1755 he married Jeanne Martin, daughter of a line of winegrowers, whose brother Guillaume, winemaker owner, married Jeanne Coppenet, Guy's sister, during the same double ceremony. Left page 2nd paragraph and previous page 3rd paragraph.
And, over the marriages of the descendants of Jeanne Coppenet and Guillaume Martin, we come to Emile Bouzereau, our grandfather, six generations of winegrowers later.

The cabinet of curiosities.

The deeds reveal some curiosities, such as extreme ages between spouses (that of the man is respectable and that of the woman much lower): the miller Jean Guérin was 57 years old when he married Marie Fagot who was 22 (ancestors of Elvire Sinful). 1st paragraph of the marriage register
But the reverse is also possible: Antoinette Teyssedre was 56 when she married Jean-Antoine Duranton, who was 20 (Jean-Antoine is the ancestor of Cécile Pied).
Or the birth of a very premature child: Jean-Pierre Guérin was born on February 7, 1755 while his parents, Jean-Pierre Guérin and Hélène Mahu (ancestors of Elvire Pécheux) married on February 6, 1755. Acts n° 5 page left and n° 6 right page

From Saint-Dizier to Hollywood.
Or Runaway Bride (1) in 1771.

Priest Tabary had prepared his marriage certificate for February 6, 1771 in the parish church of Saint-Martin de La Noue in Saint-Dizier, but he had to cross it out furiously after the ceremony, because it turned out to be no :
''... whereas the parties named therein changed their minds at the time of the celebration''
The story does not say if Marie Anne Milloy decided to follow Julia Roberts' example or if Jean Thiebauld felt remorse.
