My 3x-greatgrandmother, Henrietta "MIRES" (actually Meyer), aged 81, born Bavaria, is listed in Piqua in the 1880 census, with sons John P., age 59, and Peter, age 36, and two grandsons, Jacob, 22, and Henry, 13, sons of John. All the males worked on the "Brick Yard." They had moved to Piqua sometime between 1870 and '80 from Cincinnati, OH. I need to know where they were after 1880, and Henrietta's date of death and place of burial. Did any of the men marry in Miami Co.? Can anyone tell me more about the "Brick Yard?"
