Marija, it's not uncommon to have large families. My mother-in-law has/had seven brothers and sisters, and my father-in-law was one of thirteen kids. Most of my wife's aunts and uncles also had large families (from four to eight), so as a result, when I went to my wife's first family reunion, there were something like several hundred first cousins. No way everyone remembers everyone else, and it is a common exercise for them to start enumerating who the parents and grandparents were just to figure out where in the family tree they belong.
