Thank you so much for your response. I eventually sent off a request to the newspaper in Lansing and payed $5 each for their obits - which indicated they were buried at Deepdale. Last summer I traveled to Michigan and visited Deepdale. At first, the cemetery office said there was no record. But the lady kept digging (no pun intended!) until she found them. Apparently, the modern records only went back so far, and then you had to start looking through hard copy records. In any event, the lady was extremely helpful and she even drove out to the cemetery and helped me search for several minutes until we found their graves. I searched Find A Grave and didn't see them listed - so I assume those entries are fairly new.
