Bright sub-mm and FIR sources have historically been counted amongst the most star-forming objects in the early universe. However, unambiguously identifying a physical counterpart at other wavelengths (in particular, at the optical, where dust extinction is usually severe) has proven very difficult. In this talk, I will discuss the results of a multi-wavelength analysis of a sample of bright FIR sources. Using Bayesian inference methods via the XID+ software, which makes use of the positions of known multi-wavelength sources, we determine the best distribution of FIR flux amongst 24 and 3.6 micron counterparts. I will discuss the multiplicity of the FIR sources obtained from this analysis, and discuss the plausibility of physical associations between these FIR-bright counterparts. These results will aid our understanding the high-redshift star forming population, in particular those objects which have been blended together due to low-resolution imaging.
