Can you help identify two of these people?

This photo was taken at the 75th anniversary of the Mary Stanford lifeboat disaster in November 2003. Most of the group is known, but help with two unknowns would be appreciated. Reply in the comment below, thank-you.

From left: Tom Pope, unknown A, Eva Coleman (Southerden), Robert (Bob) Southerden, Fred Southerden, unknown B, Audrey Hill (Southerden). In the wheelchair: Elsie Haffenden (Downey).
