the 10C sample studied in Paper I which which have deep 1.4-GHz observations available (from the @2012rsri.confE..22G, @2006MNRAS.371..963B or @2008AJ....136.1889O surveys, see Section \[section:radio-data\] for full details) and have flux densities above the 10C completeness limit in the given region. This complete sample of 96 sources is matched to optical and infrared data available in the field. These data enable us to distinguish between different source types and estimate photometric redshifts for the objects. Crucially, by using radio-to-optical ratios we are able to separate radio-loud AGN, which we know dominate the extragalactic radio source population at higher flux densities ($S_{15~\rm GHz} \gtrsim~10~\rm mJy$) from radio-quiet AGN and starforming galaxies, which are predicted to begin to contribute to the source population at lower flux density levels (e.g. @2008MNRAS.388.1335W). The range of multi-wavelength data available in the Lockman Hole is described in Section \[section:multi-data\] and the methods used to match these catalogues to the 10C catalogue are described in Section \[section:fused-matching\]. Photometric redshifts are calculated in Section \[section:lephare\] and combined with available spectroscopic redshifts to produce a final redshift catalogue. In Section \[section:R\] the radio-to-optical ratio is estimated for all sources in this sample. The properties of the sample are discussed in
