I'm having trouble trying to find a way to convey that I am x years older or younger than one of my siblings.
For example, if I had a sister that's four years older than me, the first thing that comes to mind is:
Among the visiting family members was my four-years-older sister
Which just seems incorrect. The only other thing I can think of, however, is:
Among the visiting family members was my sister, older by four years.
... which also sounds strange.
