A Small World

What are the odds that two persons, hitherto unknown to each other, sitting in a meeting room in Brisbane, Queensland, Australia to discuss course design for a Masters of Integrated Water Resources Management would both have direct paternal lines leading back to Illogan? Illogan isn't the biggest place in the world, after all.

His surname is Pascoe.

(A quick look at the 1841 Census - just before those particular Pascoes migrated to Oz - shows a lot of that name living in Camborne. The 1851 has many Pascoe families living in Camborne, a few individuals born in Illogan.)
