Jerseyman,
The information in your post is excellent. Well done!
Now don't take this the wrong way ...... I have issues with the accuracy of the map if it is North up. I have found many of the survey's from that era quite accurate and full of interesting information, and the Cox survey's are no exception. He clearly states the location of her home and that map is quite a ways off. Owens Hill basically is the sand mine at Woodmansie and that map shows her home west of it. That would put her home in the middle of Lebanon which is not accurate.
One day you and I need to meet out there and we can discuss this in more detail.
