Kathy, I have Edges in my family history also. I just looked and do not see a "One Name Study" for the Edge family.
Here's how I looked...I went to my ancestor with Edge as her surname. The name Edge was prefilled in the search box at the top of the page. I clicked on the magnifying glass to do a general search for Edge. If there had been a One Name Study, it would have been noted at the top right of the page just under the list of related surnames (in a little box that said "Edge Project.")
I'm sure there are other ways to search for One Name Studies, but that is the way I do it.
