If she was born in 1910 then she does not really count. She was 4 when the first war began an still only 8 when it ended.
If you take the Society's revised definition (though still not the rather confusing current definition) that the generation is those alive contemporary with events taking place in the world, we have had at least 4 or 5 generations since she was born. For example you could say:
- Those world leaders of WWI - people who would have been at the time in the 40 years plus age braken
- The between the wars generation
- Those world leaders of WWII
- The baby boomer generation post WWII
- The modern generation born since the start of the computer age (I know computers were around before then but weren't pervasive as they are now)
