No siblings or family except for my children. I had cousins in a long forgotten life/my childhood (<6-7 years old).
They all emigrated and spread allover the world. No idea if they are still alive and I don't feel the need to trace them. I don't see any point in doing so since we've never been close. We might have met once or twice per year. I was closer with the neighbour's children.
