The second-class daughter is doing a task on the okr. world. You need to enter in the table of relatives, their professions and so on. I propose to limit yourself to a set of relatives " brothers, sisters, mother, father". The daughter enters all the uncles, aunts, grandparents. Then came the second wife of my grandfather. His first wife, his grandmother’s daughter, died long ago. The daughter named her second grandfather's wife - "adopted grandmother".
