As Toledo grew, ward boundaries changed and areas/streets could have been assigned different ward numbers. You can better understand this by checking Toledo city directories. Many of them included a ward map in the front of the directory.
Regarding cemeteries, you may want to check out the information on St. Pat's Cemetery at http://members.tripod.com/~k.noe/stpats.html
. This info may solve your mystery as to where your ancestors are buried.
