Recent analyses of cosmic ray arrival directions have resulted in evidence for a positive correlation with active galactic nuclei source positions that has weak significance against an isotropic source distribution. In this paper, we explore the sample size needed to measure a highly statistically significant correlation to a parent source catalogue. We compare several scenarios for the directional scattering of ultra-high energy cosmic rays given our current knowledge of the galactic and intergalactic magnetic fields. We find significant correlations are possible for a sample of <1000 cosmic ray protons.
