It is generally accepted that the woman who anointed Jesus in John's Gospel was a different woman than the one who anointed Jesus in Luke. There are several reasons for this belief. First, there are differences between the accounts of each incident. Second, there is a difference in the detail provided about each woman. Third, the time frame between when each event is said to have occurred differs; the event in John's Gospel is said to have happened much earlier than the event in Luke's Gospel. Finally, there are geographical differences between where each event took place. Most biblical scholars believe that these discrepancies suggest that two different women were involved in these incidents--one woman who was known to John's audience and another woman who was familiar to Luke's readers. There is no way to know for sure which story is true. However, if they are two separate events, it's possible that the woman in Luke was from Bethany, while the woman in John was from Galilee.
