Please clarify: Are you looking for Adolf Saesar and Antione Kraft or are you looking for 3 generations prior to them?
Are the dates - birth dates? marriage date? death dates?
Do you know the location of any birth, marriage death ie. country - province/region - city, town?
Are these 2 people related, and if yes, how?
Do you have the names of any parents, spouses, children, siblings?
All those things will make it easier for someone to possibly help you. I didn't see a WikiTree Id for either person, but did not check alternate spellings, do you know if either person is already listed in a WikiTree profile?
