Eli Walls Ditch runs from Georgetown, in a southeasterly direction about 4 miles to Morris Millpond.About halfway inbetween, was the 1868 residence of G. Walls, about in the middle of the present Sussex Pines Country Club.
Also, the Walls (from my previous post) that lived on Budnicks Branch in 1868 was "E. Walls".
The most detailed county map I've found is put out buy ADC.Their web site is adcmap.com and they have a full catalog.The one I use is the "pocket map" of Sussex County for $3.95. (A bargain).Eli Walls Ditch is shown on that map.
If email me at firstname.lastname@example.org, I'll email back a scan of the area.
