Adam Lemp’s third wife had a daughter from an earlier marriage that later married a Gottfried Pfaff. They both died, so Adam raised his step-grandson, Otto, who eventually unofficially took the Lemp name. He’s buried in an unrelated family plot out in New St. Marcus Cemetery in Affton. He seems to have little relations with the more famous branch, buying plots far from Bellefontaine Cemetery, where the rest of the family is buried. More on this in the future.
Two out of the six graves are still unoccupied.
