My current toilet is measuring at 11 inches even from the wall (not the molding) to the center of the bolts. Looking around I see a lot of people saying that they saw somewhere else that a 12 inch rough-in will fit, possibly with an offset flange, but I'd like a more authoritative answer if possible. My house was built in 1900, so a non-standard size wouldn't really shock me.

Since the ultimate solution may be to open floor and cut out the affected drains, lets hope it was only a poorly sealed cap.. Its worth a few experiments:
Screw in a wedge anchor in center (of cement in drain) and use several pry bars or jacks to lift slug out
Drill a few inches down with a 2" coring bit (rented with a SDS max rotary hammer at local orange big box). Repeat across the face of drain, being careful not to drill through drain. Try chisel and point bits to see how deep it extends. Shop vac pieces as you go, in case you breakthrough (think positively).
- Call emergency hotline on the extended home warranty policy (its in with the mortgage papers)
Given multiple issues there, I think the correct and possibly simplest, albeit messy, solutiion is going to be cutting the floor open and putting the pipes where you need them.
Concrete is not forever.
