Mothers maiden name-don't know Female, White, Widowed Husband-Henry Dupont Informant was Evelyn Miller-I would think this is her daughter. Burial-St. Stephen on June 12, 1933.
If you go to Campbell County Kentucky GenWeb and type in Dupont in the search box there is some information about death, burial, and baptisms for your family.If I may make a suggestion you may get more of a response if you post to the genforum state forums with the information you are looking for, Kentucky, New York, Connecticut, since that is where your family is from.Numerous people helped me on the state forums when I first started out when I had very little information about my family.Well happy hunting and good luck.Kathryn
