[Theme: Twenty Eleven] Entry title header question

I’m setting up a site of about 7 Pages. I want to delete the title that’s just below the horzontal menu bar and just above the main paragraph. The header in Twenty Eleven seems to comprise a title and tag line at the top, a search box, a 1,000 x 288 Feature Image, a horizontal bar for navigation menu, and below the menu bar an “entry title.” Just above this entry title seems to be a copy box that’s identified by my Firebug as <div id=main”>, which is blank, it has no text in it. I want to delete or minimize that entry title and use larger font-size heading to begin the body copy. But I can’t seem to figure out how. I reduced the “entry title” size to 6 px, I colored it white. And I minimized its margins thinking that it was preventing the paragraph heading from using a taller font size. I suppose I could figure out how to edit the text of this “entry title.” As it’s templated, it simply echos the name of the page, which is also in the menu bar. But I can’t figure out how to change that so it’s unique to each page.
