What’s the age gap between you & your siblings?

[Applesinmyhouse]

Just idly wondering.
There’s 7 years between my sister and I, and a whopping 15 years between my brother and I.
Can anyone beat that?

There’s 6 years between my siblings and me (4 of us altogether).

My sister’s youngest child is 20 years younger than her oldest (all have the same father).
