Family talk:William Gray and Minerva Price (1)

Pam, I deleted my tree and started over with William Gray, m. to Minerva Price. On their Family page I entered the 1880 DeKalb Census as a Source, S1. When I click on Preview I don't see any reference of "S1" but in the Edit mode it is still there.  ???Look at it if you will and tell me where the train jumped the tracks. Sorry to be a drag on you!
