Things start to get interesting now. As you’ve seen before, it makes a difference whether a relative is older or younger. It also happens that, in Korea, the male side of the family is linguistically dominant. I didn’t make the rules, so please don't complain to me.
Not that being the eldest male child is without responsibilities—if a husband dies, the elder brother traditionally is expected to take care of the widow and children. In fact, that’s why the father's older brother is referred to as 큰아버지 or “big father” as you will see on the next page.
In addition to all of this, it makes a difference (on the male side) whether the brother is married or not. Take a deep breath and proceed to the next page.
