Following Matt's suggestion to find pictures of people with your surname, I searched Google images for 'hourihan' and came across some interesting photos. The weirdest is this photo of Chip Hourihan from the Exeter facebook of 1979. I don't know Chip, but the photo oddly looks a bit like me. Perhaps we're related? Also I found a reference to Hourihan of Ireland in this photo from a clothing catalog. Hourihan of Ireland makes, "[c]apes and wraps in luxury blends of precious fibers." This is one of those times I just love the web. I want a cape from my kinfolk.
