History
Formed in 1876 from Young County
An old deed may name a county that no longer exists, or a boundary that has since moved.
Crosby County was created from Young Territory in 1876 but was not fully organized at first, attached to Young for judicial and other purposes. The county was detached from Young in 1881 and attached to Baylor, then fully organized and detached from Baylor in 1886. Between 1887 and 1891, several counties were created from Crosby's territory, including Bailey, Cochran, Dickens, Floyd, Hockley, Lamb, Lubbock, Motley, and Dickens.
