I've made the connection to Piquerie/Piquery. Eulalie's aunt (Marianne Simon) married/had children by the mulatto Francois Piquerie. I can't find the connect to Boilleau. Another aunt, Genevieve, married Antoine Registre. Her father, Nicolas Simon, was married to Castillon. Where does Boilleau come in? Does Nicolas Simon have another sibling that I'm not focusing on? (And by the way, I will never try to convince you that the truth is other than as you have presented it.) If the other voices rise up, please ignore.
