This is dedicated to my dear cousins, descendants of Martial Caillebotte.
It has long been my belief that the 2nd and third wives of Martial CAILLEBOTTE (the father of Gustave, René, and Martial) were related in some way. As my research continued, I began to suspect that the second wife, Eugénie Séraphine LEMASQUERIER was likely the aunt of the 3rd wife, Cèleste DAUFRESNE, whose mother also born LEMASQUERIER.
Special thanks to our cousin, Philippe PINSON de VALPINÇON, for helping me locate family birth and marriage records and proving my beliefs.
We knew that Cèleste DAUFRESNE was the mother of Gustave CAILLEBOTTE, René, and Martial.
We knew that the mother of Cèleste DAUFRESNE was Marie Cèleste LEMASQUERIER.
We now know that Marie Cèleste was born 12 Jul 1797.
We now know that Eugénie Séraphine LEMASQUERIER, was born 12 Jul 1813, and was the sister of Marie Cèleste, both having same parents.
Finally, we now know that Eugénie Séraphine LEMASQUERIER was also born as a twin, with her brother, Eugene Joseph LEMASQUERIER.
I am posting this via an iPhone, and will post more information in the future, as I transcribe these documents. Please forgive any typos I made with my thumbs.
it sounds as if Eugenie was not so old than Céleste? since 16 years separtes Eugenie from Marie Céleste
