This Land Is Your Land
Posted by Diane
Do you have an ancestor's deed or land patent? The strange-looking land description containing letters and fractions is called “aliquot parts.” If you can decode the description, you’ll be able to figure out exactly where your ancestor’s land was.
Aliquot parts is an important element in the public land survey system (PLSS), also called the rectangular survey system, which was used to survey and divvy up land starting shortly after the Revolutionary War.
States with land surveyed under the PLSS, called Public Land States, are Alabama, Alaska, Arizona, Arkansas, California, Colorado, Florida, Idaho, Illinois, Indiana, Iowa, Kansas, Louisiana, Michigan, Minnesota, Mississippi, Missouri, Montana, Nebraska, Nevada, New Mexico, North Dakota, Oklahoma, Ohio, Oregon, South Dakota, Utah, Washington, Wisconsin and Wyoming.
That's everything except the original 13 states, Maine, Vermont, West Virginia, Kentucky, Tennessee, Texas and Hawaii. (Parts of Ohio were surveyed with the old metes-and-bounds system, too.)
The PLSS established principal meridians—imaginary north-south lines—to serve as the starting point for surveying each 24x24-mile tract. A tract is divided into 16 townships; townships (23,040 acres) contain 36 sections, each 1 square mile (640 acres), like this:
A section could be split into halves, quarters or other parts. A description of your ancestor’s subdivision on a land record might look like N½ SW¼, which you’d read as “the north half of the southwest quarter.”
Here’s an example of how land might be divided and described in aliquot parts:
