The last thing I can point you to is a marriage application, unfortunately not transcribed online though.
In the Greene Co IL site (not MAGA) but many links failed to work for me, is updated marriage books/applications which cover 1901-1915. In the application section it states:
Fred Newingham/Carrie "McGinniss" book 3 page 38 box 5503.
You may be able to order this application via the courthouse if there is a chance it may be helpful.
My uncle does many of the cemetery searches and transcriptions/photos for his work through MAGA (Morgan Co Genealogical which tries to cover also the surrounding areas). Yes, the cemetery links online have made it so much easier relatives from afar to be able to 'visit' long ago grave sites at a click of a mouse. I'm not sure who has gone all the volunteering over in Greene Co, but they too have done a fantastic job of going out and reading/recording .
Good luck to you in your searches :)
