My granny knew only a few things about her Aunt Cecile: She married an Ernest Giroir, had a few boys and died young.
Cecile was Mary Cecilia Gautreaux/Gauthreaux. She was the only daughter of Cordelier and Merante Aucoin Gautreaux/Gauthreaux.
I’d never found any trace of Cecile after she left home until I stumbled across notes Granny made that mentioned her husband’s name. Those notes led me to her marriage certificate. Her father and uncle witnessed the marriage.
Then I found Cecile’s son: Adolphe Adam Giroir.
It’s nice to add them to the family tree.
