Narrative:

Planned for a part 91 flight with two passengers from btm. Events leading to the takeoff roll were normal and included at least 3 radio transmissions over CTAF; including one to the cessna (aircraft Y). The specific communication related to our intent to depart the area to the west; as was he; and our respective separation enroute. I responded that we would be well out of his way. We started our takeoff roll on runway 33. Another cessna (aircraft Z) was taxing along the parallel taxiway and the first cessna (aircraft Y) radioed that he would be taxing to runway 29. After the 80 KT callout we both noticed that a cessna was moving quickly and about to cross our runway on taxiway D (approximately 4;000-4;500 ft from our departure end). The pilot flying (captain) initiated an early rotation at approximately 90-95 KTS as the pilot not flying (first officer) increased torque to about 120%. The airplane lifted off sluggishly; but in control. The pilot flying altered course slightly to the left and behind the cessna. I (first officer) saw the airplane to my right on the centerline of our runway with a vertical and lateral separation of 50 ft or less as we crossed taxiway D airborne. Communications with aircraft Y after this incident revealed that he thought '… a piaggio; departing 33' (how I make my radio calls) was the 'other cessna' still taxing down the parallel taxiway.

Title: P180 flight crew departing Runway 33 at BTM reports critical ground conflict with Cessna single crossing on Taxiway D. Early rotation prevents a possible collision. Three aircraft were involved in this incident and all three were in communication on the CTAF.
