History

Formed in 1887 from Tom Green County and Martin County

An old deed may name a county that no longer exists, or a boundary that has since moved.

Glasscock County was created from Tom Green County in 1887 but was not immediately organized, so it was attached to Martin County for judicial, surveying, and other purposes. In 1889, Glasscock was detached from Martin County and attached to Howard County for the same purposes. The county became fully organized and independent in 1893 when it was detached from Howard County.

Boundary changes from the Newberry Library, Atlas of Historical County Boundaries.
