Can you solve a mystery?

We have been looking through our storage and have run across a number of headstones that don’t seem to have a home.
They may have been left behind when people moved from the city or abandoned when relationships changed.
We would like to reunite these memorials with the people who bought them.
The list shows the names on the markers along with the dates of birth and, where available, dates of death.
The longer list is of bronze plates. To be set in Topeka Cemetery, these must have a granite base. The second list is of all-granite markers.
If you know any of these people or can shed light on where they may be buried, please send us an email.
