Lena I don't know if you are aware of this. There are death, birth, and marriage index records available online for Cass county. They have been transcribed by volunteers, like Cathy, who did the particular page that Platt is found on. Although the index may have errors on them, they are a very valuable tool for those of us that are from outside that area. They are transcribed exactly as they are printed, when possible. There are times when the printing cannot be read, and there may be blanks or even ??? in those instances. These transcriptions are very difficult and time consuming. Please feel free to check these index for names and dates. An omission does not mean that there is no record, but if the name is there, there is most likely a record available. Good Luck Aaron D.
