I believe someone died in Polk County but can't find her death record. I believe it was Polk County as her children died there a few years after she died. Does anyone have any suggestions for me as to where to look for a death record for this person? Her name was Martha Bearsley Cranshaw and she died in 1875. Her 2 children died in Marsh Lake, Polk county in 1880 and I found their death records. Any suggestions will be appreciated.
