This article raises the importance of the use of ICT in the management of citizenship and especially the identification of the individual in a lineage based on biometric elements. To do this, we propose a modeling platform of the family tree that associates the blood group and an inherited disease, sickle cell disease. These two elements are typical examples used to identify a descendant or establish the descent of an individual in ancestry or descent. These elements can be known at the birth of an individual and mentioned in his personal file in the construction of the family tree. They would be able to prove at this stage his filiation with his ancestry already knowing the similar information of his ascendants. This same information could also be very useful for medical services, documentation or police and serve a variety of purposes.
