I received the above copy from a 'cousin' of Kirk's who is a Dollaway descendant and lives in Lowell, Michigan. She wrote on the picture "Tombstones made out of marble candy boxes in candy factory where their father Willis worked".
The Dollaway babies are buried in Rolfe Cemetery, Lowell Township, Kent, Michigan, which is located at 9790 E. Fulton Street (M-21), to the west of Lowell. Rolfe Cemetery has been known as Roth Coons Cemetery, Simpson Cemetery and Mathews Cemetery.
The tombstones and their inscriptions from top left to bottom right are:
A few years ago, M-21 was rebuilt and the road moved closer to the burial sites. The headstone on the right is Clarence Dollaway's and was broken when a car slid off of M-21. Tim Holtz, a Rolf descendent, decided to restore this cemetery and create a new transcription which can be found here.
