Jim, This could be a potential ground cover to plant over early spring ephemeral bulbs. Assuming those small runners with non-compound leaves that are heading out towards the brick sidewalk are part of the same plant, then this plant looks like some species of dimorphic Parthenocissus. The leaf veining seems a little off but that could be due to the atypically blunt leaflet tips. Anyway, this is the answer I've convinced myself of so I can stop thinking about it. Please let us know when you find out the correct identification.
