Can we dig an old basement deeper?

Hi, We own a house that is over 100 yrs. old with a full basement. The foundation is limestone. The basement is barely 6' in height. Is there any way to deepen our basement so we could make it a finished basement? It appears that we would have to dig below the footings.
Well, here's hoping someone has some ideas.

Underpining the existing footings should be handled by someone with experience. Excavation at a 45* angle from the footing and necessary concrete will leave the new finished floor area smaller than the perimeter of the foundation walls by about two feet if you want eight ft. head room. If you are doing it yourself, research it through, including the type of soil you are on.
