I almost know that area -- I checked it out online and thought I might do some riding there because my nephew recently moved to Maryland and was staying in a temporary rental not far off Edmonson in SW Baltimore. But he ended up finding a more permanent place to live south of the city in AA County.
This will probably not help you decide on a route, but I had an interesting experience last night. My LBS had a ladies' night, which they do monthly from spring through fall. There were a lot of women there, and we went around the room introducing ourselves and stating our favorite place to ride. Almost every one of them said her favorite place to ride was a local trail in the area. Some of them ride with their kids and others are just getting into cycling or getting back to it after years of raising kids, but I was still surprised at the lack of road riders.
It could be that a women's event at an LBS tends to attract more women who are less experienced cyclists, for a variety of reasons. So maybe the trail ride would be a good way to start, and then you could gauge interest in a future road ride. Though on the other hand, a 10-mile trail ride might only attract women who are not interested in road riding. I don't know.
