Same deal here
We have a house built in 1925 that the owners did a similar thing to and removed a wall that NEEDS to be there. There are trusses in the attic (from what we can tell... but who knows with those people) but the ceiling is still beginning to show signs of falling in (see my gallery). Anyways, be careful when you do this, make sure to put a beam along the ceiling to give a little more support... depending on the age of the house then you'll need to do some MAJOR patching, etc... (ours involved the ceiling and the floor!)
Good luck with it and I hope it turns out for ya.
