The study of the archival documents allows us to establish the fact that Măcărescu was an old aristocratic boyar family from the Moldavian territory over Prut, which actively fit into the life of Bessarabia after the annexation. Documents submitted to the Commission instituted to verify the boyar social rank had proved that indeed the reprezentatives of the Măcărescu belong to the social category of the nobles, being descendants of Mihail Măcărescu, a royal clerc. During the nineteenth century the representatives of this family fought for the confirmation and the reconfirmation of the title of nobility. We also can conclude that the Măcărescu family members had pretty large properties, have held various positions in the Russian imperial administration. In addition they were actively involved in the social life of Bessarabia. In conclusion we can see that Măcărescu family history contributed to the building of Bessarabia in the nineteenth century along with other aristocratic families and the entire population of the territory between the Prut and Dniester.
