Hi,
I've searched through the records ( no index the originals ) and pretty much found what Jorose found except for one or two things.
So for the birth of MASSOT Valentin in December 1872, he was born the first and recorded the 2nd.
The information you have are correct.
The witnesses are MARIANNE or MARIONNE Michel Léon the public teacher, 45 year old and ? FOUILTEUT ? Victor, 49 year old farmer.
I found the marriage certificate for MASSOT Valentin and VASEUX Nathalie Appoline Marie Anne. I don't translate it all but I give you the lines :
27th January 1872, 4pm.
" I Arsène Mouton having the quality of public officer of St-Martin-de-la-Connée received : "
MASSOT Valentin Félix Pierre, 27 year old moulder living at Orthe in the village ( Orthe is a hamlet )
born at Saint-Aubin-du-Désert May 10th 1844 according to the birth certificate he presented. Son of MASSOT Jacques, 63 year old carpenter ANDRE Marie, no profession 61 years old. They seem to be alive though they are not said to be present.
VASEUX Natalie ( written this way this time ) Appoline Marie Anne, 25 year old cook living at Orthe in this village. Born at Saint-Thomas-de-Courceriers, June 2nd 1846. Daughter of the late VASEUX Pierre who died at St-Thomas April 1st 1863 and BOUVIER Appoline, no profession, 47 year old living at St-Thomas.
Then there is an explanation saying that all documents are conform, no opposition to the union. They both say yes to each other?
Presence of MARIONNE Michel Léon, public teacher, 44 year old.
SIMON René, carpenter, 49.
PRUDHOMME Frédéric, carpenter, 28.
BESNARD Jean-Baptiste, 49 ( could not read his trade ).
They all signed.
This record is available at Saint-Martin-de-la-Connée's records, page 456 for the 1863-1872 registre.
So that opens a lot of opportunity with birth dates/places and the death date of Nathalie's father.
Geneanet and Ancestry are good but most departments offer parish and civil records available online for free like for yours. But you need to read/understand French though. If you want more help you can ask again or by private message. I hope this helps
