I would suggest to you that you need learn how to do web searches. I'm not saying that to be snotty, i am really mystified as to how you can say you've exhausted the web.
I did a Google search on "North American Phalanx," and Google returned 40,300 results in .22 seconds.
This Wikipedia article on the North American Phalanx was the number one result.
A search for "Charles Sears" returned 606,000 results in .38 seconds at Google. However, the name Charles Sears is a little too common, apparently, and i did not immediately see a reference to the North American Phalanx boy--i suggest that the common name Charles combined with the not uncommon surname Sears is too ambiguous for an easy search. I am certainly not going to look through 606,000 results to find for you what you are looking for.
So i did a search for "Charles Sears+North American Phalanx." Google returned 1680 results in .38 seconds. I'm not going to do all your work for you, so, go to a search engine (and i recommend Google) and put this in the search window:
Charles Sears+North American Phalanx
I cannot escape a suspicion that you are just jerking us around claiming that:
I believe I have exhausted all internet sources. In fact, i suspect you may have gotten lazy and just dropped in here to get your work done for you.
If not, however, i strongly advise you, in all seriousness, that you do a web search on "web search techniques." It was so damned easy to find what you wanted that i really cannot understand why you didn't find it yourself.
