I found something but I am not sure it's the right couple because the given name of the groom is different. A Jean VILLENAVE, fisherman, 22 years old, married a Marie GLIZE, 18 years old, in 1886 in Soustons (Landes). 04/MAR/1886. Both of them are natives of Soustons. He was born on March 20th 1863 to Dominique VILLENAVE and Jeanne DASSé. She was born on Marth 25th 1867 to Raymond GLIZE (+1876) and Catherine DOUAN. Raymond GLIZE was a carpenter. In 1886, his widow is a cook in Berson (Gironde). Marie GLIZE is a domestic.
The father of Pierre Henri VILLENAVE is named Auguste VILLENAVE in his birth record in 1888. He is 25 years old and a fisherman = born circa 1867 and his wife, Marie GLIZE, is 21 years old = born circa 1867. She is a day worker.
The father is away and the declaration is made by a midwife (often a source of errors).
I think you should order a copy of Pierre Henri VILLENAVE's marriage record in 1924 to check the full names of his parents.
Jean VILLENAVE had a twin brother Pierre VILLENAVE. Their parents got married on October 2d 1863 in Soustons..
