I am looking on information on the Lachance's from or around the Potosi, MO area. Know that Elmer and Gladys Lachance were biological parents. Have located graves of them in Potosi. Know that Elmers' father was Ferdinand "zep" Lachance, and mother was Mary Schutte, and Ferdinands' parents were Joseph Lachance and Mary Boyer, that is as far as I have been able to trace positively. Any assistance you may be able to provide would help me out so much. Want to find out heritage for myself and children, etc...
