In addition to what Hal and Scott said, I recommend that you do not angle your flashes toward the center of the group. That will make the center brighter than the ends where they don't overlap. It will also create a flash shadow on one side of each face, and if the umbrella angles are severe enough, the shadows will project onto the adjacent person.
I get more even lighting across the group when when I point the umbrellas straight ahead and place them about half way between the camera and the end of the group, still aimed straight forward.
Your umbrellas will always overlap to some degree. There is nothing you can do about it. But if you think about it as you place your umbrellas, you can avoid the worst of the uneven lighting and the flash shadows. If you are still getting flash shadows, move the umbrellas closer to the camera.
