From the Annals of Lancaster Co, PA: "Aaron lived at home until he was twenty-five years of age, and during his boyhood received a good practical education in the common schools. He commenced farming in Clay township, continuing thus for eleven years, after which he moved to Brunnerville, the place where he now resides. He bought out the foundry and machine shop of Peter Bruner, who died in 1868, and has carried on the business up to the present time, meeting with substantial success. On July 31, 1898, the shops burned to the gound, but within ninety days Mr. Wissler had the re-building so far advanced that he was able to resume business. The incident is characteristic of the man, for he has throughout his career displayed an energy of purpose and enterprising spirit which fully account for the success with which his efforts have been crowned."
"Mr. and Mrs. Wissler are both members of the German Baptist Church. Mr. Wissler is one of the most respected citizens of the community where he has spent a long life of usefulness."
