Lane County has documents about the early development of Staffordshire available to review in full if you wish. You can find them digitally through their Land Management Division Property Records Online website (link below).
On the far left hand side of the webpage, there is a dropdown menu for “Less commonly used documents”.
The last option in this dropdown menu is a choice for Subdivision Files.
This brings up an option to type in the “Subdivision Name”, which you will want to use “Staffordshire” to bring up the relevant document
