I am looking for information about my great uncle, Peter J. Diem (born in July 1868), his wife, Mary A. (Murphy) Diem (born in February 1870), and Francis Mary Diem their daughter (born in November 1891). The family lived in Buffalo, Erie County, NY for many years. Mary Diem died in September 1950 and her daughter Francis died in October 1985. Both are buried in Mt. Olivet cemetery in Tonawanda, Erie County, NY. Peter's father was Andrew H. Diem who emigrated to NY from Germany in 1854.
