I have Agnes marrying Edwin in 20 Feb 1898, but no others. We are related though her daughter Margaret
I found the profile for Agnes on WikiTree https://www.wikitree.com/wiki/Ruffin-370
It looks like this could use some work, as there is both an Edwin and an Edward. Based on your Ancestry tree sources for his WWI draft and social security, Edwin seems correct.
There is no current profile manager for Agnes. You would be more than welcome to join us on WikiTree and work on these ancestors. It’s a great way to share your corrections with your cousins, and to find those cousins.
