In the case of individuals who become symbols for a cause, I don't see that it matters whether there is enough information for a biography or whether it follows the exact format for a formal biography.  Often these events take on a life of their own, and in a span of years, trigger formation of organizations and legislation invoking the individual involved in that particular event.  The alamo is not just the alamo.

SEO optimization should be taken into consideration with these names, at the very least as a courtesy to the readers who are trying to find information on the topic.  When naming articles, the effect of search engines, particularly Google, is often taken into account, especially when trying to determine Primary Topic--in other words, which article gets to sit at the premium name, and which gets to be listed on a disambiguation page with qualifiers in parenthesis. I was always unhappy that the Guantanamo prisoner Mohammed al-Qahtani got the premium spot, while the Saudi dissident had to be satisfied with Mohammad *Fahad* al-Qahtani.  But the ghits bear out the popularity of the first name, so it would be hard to make an issue of it.
