Orange Free State Birth Registers are available in the Orange Free State Archives in Bloemfontein. Below is a list of the towns for which they have registers.
The Bloemfontein Archives will only release birth register information up to 1925 and have a 100-year cut-off period. They will not photograph or email the documents on your behalf and will require someone to physically visit and obtain a copy or photograph the register.
