Yes they do. My sister has a son and a daughter, they live ten minutes away we see them often. My step brother and step sister both have a son and a daughter they live in Baltimore, which is about 30 minutes away we see them mostly in the summer.
Most of my extended family (aunts, uncles, cousins, and grandparents when they were living) live in Georgia. We moved around alot, my parents were in the Air Force. I rarely got to see my cousins. Now I keep in touch with them by phone, email, and Facebook and see them every summer at the Family Reunion in Georgia.
Nope. They have only seen them a few times and most of them were not good. Now I don't speak to my brother or should I say he doesn't speak to his side of the family, so we don't see them at all. I know growing up we were military and moved around A LOT. I saw my cousins only once a year. But now I talk to them all the time on Facebook.
