I am looking for information about Hyacinth Renault (assumed to have been born in France/Belgium) father of half sisters Lucien Renault (born in France or Belgium) and Marie Josephine Renault (born in Kobe, Japan on Jan 10, 1905). The half sisters had a cousin who visited their descendants in the 1980's on Northern California by the name of Martha Dewrell. Martha and her sister lived in Spain at or around the time of their visit. Marie Josephine Renault's mother is believed to have been called Goto. Family stories pro port that Hyacinthe Renault was either a sea captain or an ambassador to Japan.
Any additional information would be appreciated.
