History
Formed in 1872 from Allegany County and Allegany-Garrett County
An old deed may name a county that no longer exists, or a boundary that has since moved.
Garrett County was created on December 4, 1872, from Allegany County. The county was named after John W. Garrett. When the boundary between Garrett and Allegany was first surveyed, it was run too far west, making Garrett smaller than intended; despite efforts to correct it, the original survey line became the legal boundary through long observance.
- 1872Garrett County created Garrett created from Allegany. As demarcated at the time (and mapped here), the Allegany-Garrett boundary was run too far west, making Garrett smaller than it would have been if the legal boundary description was observed. Despite considerable controversy and numerous attempts to move this line to the course originally prescribed, through long observance the original survey line became the effective, legal boundary.from Alleganyfrom Allegany-Garrett· Md.
