Here is the burial record for Margaret Mann, who was married to Jacob Foutz. It is found in the Pleasant Grove City Cemetery Sexton Records, 1866-1981, p. 18 (Family History Library microfilm 1,654,384). Image is cropped. Margaret Mann is my 3rd great-grandmother.
We learn several things about Margaret in this record. Her birth date of Dec 1801 conflicts with data found in other records (1802). Her birthplace is given as Pennsylvania and her father’s name is David Mun [sic] and the date of death is 5 Aug 1896.
Many beginning researchers limit their search of cemetery records to headstones or cemetery databases online, but one should always check in the cemetery office for other records. Cemetery sextons or office managers usually have burial registers and /or card files with much more information than one will find on a headstone. They may also have sales records, maps with names on them, and copies of burial permits. Often there is no headstone on a grave, so looking for these other records is essential.
Remember, also, to check for funeral records at the local funeral home, and obituaries in local newspapers. These can often be found on microfilm at the local library. Just call the library and ask the librarian what issues of the local newspaper are on microfilm, and if they can be borrowed through inter-library loan (ILL).
