I may be telling you info. you already know...forgive me if I am.But the Ackerman line can go WAY, WAY back in Paterson, NJ to the founding of Paterson.There is a book, the name escapes me at the moment, poss. The History of Paterson, NJ? Which may give you background.I would think that as long as they have been there, that there should be more recent info. of same family. Poss. stating the obvious: check Family History Center of LDS library for poss. books.
