Three leaves on a stem

Leland Meitzler at Everton Publishers Genealogy Blog - found statistics on places in the United States named Shamrock!

My first thought was to use the Geographical Dictionary (my 1977 Websters Geographical Dictionary only lists 1 place in the US named Shamrock) but how many folks can lay their hands on a print edition - at home no less.

Then I thought about the World Almanac in GALILEO - no luck there noting locations in the US named Shamrock.

So I skimmed the rest of Leiland's entry- and (well, go read for yourself the sources he used). See if you would have thought to use those sites!
