Census Records
Frio County was created in 1858 so the first census record was in 1860. Before that, check in Bexar County. Copies of census records and searchable indices for them are available at FamilySearch.org.The 1850 census was the first to name all family members and gives ages, places of birth, values of real estate, Color (White, black or mulatto) and occupations but also has columns for married within the year, attended school within the year, person over 20 who cannot read or write and "Whether deaf and dumb, blind, insane, idiotic, pauper or convict"; which can make interesting notes.
In addition to the 1850 columns, the 1860 census asked for value of personal property.
1870 This census added columns for born within the year (asking for the month), whether parents were foreign-born and two questions about men over 20 (voting information). Folks with a free account can search and view this census at FamilySearch.org.
For 1880, we have the first census to ask for marital status and relationships within a household.
The 1890 Federal Population Schedule burned before it could be copied; there are no existing records for this county.
The 1900 Federal Census is the first census to ask for years married and asks women how many children they've borne and how many are living. It also asked for the month and year that each person was born, the year they immigrated and whether they own or rent their homes. There are also colums for street addresses but they were not generally used in rural areas. The index to this census is available to everyone with a free account at the LDS on-line library.
There are copies of the 1900 Census images in our Archives.
