If you see your name written differently in different deeds. This does not mean that they are not your ancestors.
Only parentage can determiner one ancestor identifies with another!
Sons and daughters : Principle that defines the transmission of kinship. There is a filiation link between two individuals when one descends from the other or when both descend from the same person. All the social processes that define kinship between individuals or membership of a social group from generation to generation.
Natural parentage : The relationship between a child and its father (paternal filiation), mother (maternal filiation) or both (parental filiation, which is only used when the child's parents are not legally married.
Illegitimate parentage : As long as an illegitimate child has not been voluntarily recognised or has not established his filiation in court, he is legally a stranger to his father and mother, who are not obliged to feed, support or educate him. He or she is not entitled to inherit from them, but like any foreigner, he or she may receive gifts from them or be made their legatee.
As long as your ancestor has a fairly common name, you should not fall into the trap of homonymy. Often the repetition of the same first name can cause problems. You need to cross-check your sources!
Homonymy : The quality of being homonymous.
Namesake : Said of a person, town, etc. that has the same proper name as another.
Age: This is often recorded in the records of marriages or deaths, for example, and can be approximate.
Don't rely on the year, especially for older documents.
Search for birth certificates within a range of 10 years before and after the estimated date.
The home
The marriage had to take place in the commune where one of the future spouses lived. Traditionally, under the old regime, marriages took place in the bride's parish.
Please note: domicile does not necessarily mean place of birth.
