Who has the largest age gap between siblings?

18.5 years between me and my elsdest sibling. Same parents, no divorce.

We are very close. My parents would send me to stay with my sib during the summers when I was about 8-16 so we would develop a relationship.

Other sibs-

11 years older

8 years older.

Also, close.

My wife is over 17 years older than her younger brother, and there are no other children between them. They have the same parents. Their relationship is much closer to parent-child than a typical sibling relationship, which I suppose isn’t a huge surprise.

I have a half-sister who was born the day before my 17th birthday. I also have a twin and a brother who is 3.5 years younger than me. That brother is the closest in age of all of us to the half-sister, who also has siblings on her mom’s side. So, 13 years between youngest and second youngest. Youngest is the only one who lives near me.

Her mom is one of five. There’s 27 years between the youngest and oldest in that family and, in fact, there’s 9 years between the youngest and next youngest. Same parents for all.

My BIL is 17 years younger than his only (full) sister. She’d love to be maternal towards him but he’s not having it.

My half-brother is 16 years younger than me. I was too busy being a teenager to pay him much attention when he was a baby, then I moved out, then the parents got divorced and little bro moved out with his mom. So we weren’t at all close when he was a kid.

When he was about 10, he and I and our dad took a road trip to visit relatives. It was the most time I had ever spent with my brother and I found out what a cool kid he is and how much I enjoy talking to him. We’ve been pretty close ever since although we live 4 hours apart.

My grandmother had two close in age and then waited 15 years and had two more. No steps, either.

It isn’t the same thing but still weird in my mind. I have a 74 year old brother in law. I am 34.

I’m 13 years older than my youngest brother.

My mom’s 13 years older than her brother, who’s 13 years older than me.

All of the siblingage involved is full, not half.

I am 18 years younger than my oldest sister. She is my half sister, but we are very close. I am the youngest of the crowd, a total of six. Actually I am closer in age to her oldest child than I am to her. There are fourteen years between my niece and me.

I’m 16 years older than my half brother. He’s 6 now and I’m 22 and I’m going to try and get a little closer to him since I was away at college for most of his life.

I’m the youngest of four and my oldest sister is 16 years older than me. We’re all from the same family unit. The breakdown goes like this: oldest—~2 years—second oldest—7 years—sister #3—seven years—me. Oddly, there is a seven-year gap between my husband and his closest sibling as well (he is the youngest). The rest are spaced differently from my family though.

Obviously I’m not going to win the thread, but my brothers are/were 11 and 10 years older than I am (I say “were” because the younger of the two is deceased). My parents say I was planned, and I have no reason not to believe them, but I was not close to my brothers. I’ve heard that a seven-year difference is the “cutoff point” for siblings to be close.

My father is fifteen years older than his younger brother. Full brothers; his mother was in her early twenties when she had my father and in her mid-thirties when she had his younger brother.

Having siblings fairly spread out runs on that side of the family, as my paternal grandmother was around sixteen or seventeen years younger than her oldest brother, and there was a range of about twenty years between the oldest and youngest on my paternal grandfather’s-father’s family.

My brothers are 10 and 15 years older than me. The eldest moved out of the house and into our grandparents’ when I was around a year old, so we’ve never been really close, although we’ve always had a good relationship. I’d say he’s more like an uncle-type figure in my life. I’m fairly close to my other brother, though. We live 5 houses apart and talk nearly every day.

I know one of my uncles is at least 30 years older than his youngest sibling. He had children of his own before his brother was born.

I’m 20 years older than my youngest sibling. I’m 18 years younger than my mom. Who is 20 years older than her youngest sibling. This is a family tradition I have no intention of carrying on.

My oldest brother was 24 years old when my little sister was born (same mother, different fathers). There are five of us, I’m #4 and will be 30 this year. My little sister will be 16 a couple of days prior to that.

Also, my oldest brother is only four years younger than our stepfather.

I had an aunt and her niece in my first grade class. The niece was a few weeks older. That was disturbing.

I am my father’s oldest and am 28 years older than his youngest. My son is older than his uncle.

My wife is 18 years older than her brother. Her mother waved goodbye holding her infant son in her arms as my wife went off to college.

They’re cordial, and share a concern about their elderly father, but not what I’d call close.

I’m… 20? 21? years older than my youngest sibling - half sister.

There’s four years between me and The Boy, and then Leah would be a couple of years old now. I dunno exactly how old. Haven’t seen or spoken to dad in about a year or so. I think she might be three this year. Maybe. Which gives us 20 years difference, at the least.

How well can you get on with a two year old you don’t see?

I’m about 18 years older than my half-sister. It’s really like having a (really adorable) niece. It doesn’t help much that I live a couple thousand kilometers away.
