Look under "Databases & Links Library", and enter "necrology" in the search field. This site provides obituary information published in Cleveland Ohio newspapers over the last 100+ years.
The obits for both John & Sophia Krakow are there, along with several of their children (Lena Wearsch, Frieda & Charles Kleve, Charles W. Krakow, and perhaps others). John and Sophia were buried in the Avon Lake Cemetery, near where I live. The obits will provide the date of death of several family members, as well as information on their children.
