Something you might want to know about the information you are looking for.
It's extremely important to have the name of the person of course and the birth date is always good, but more important than the birth date is the place of birth or at least narrowing it down a bit more than region.
Alsace is one of the smallest regions in France and it still has 1000s of villages and therefore a conservative estimate for finding the birthplace is well over a thousand hours.
Everything is handwritten so it's slow going regardless.
