I've only ever met twins-normally there were 2-3 in our year group. I knew 2 sets of twins from the same family too.

My grandmother was a fraternal twin - her name was Edith and her brother was Kenneth. My uncle (her son) was a fraternal twin as well but they were born really prematurely and his twin died :(. My uncle is John and his brother was another Kenneth, both family names.
There's 4 sets of twins in my year/grade at school.
Identical girls: Elys1@ and Le1l@
Identical girls: Danielle and Lauren
Identical boys: Lewis and Ben(jamin...I think)
Fraternal girls: Kirsty and N@talie
I also know two other sets of identical twin girls (I just realised I know quite a few of those) - Alexandra/Lexi and Danielle, and Beth and Amy.
As far as I can recall I've only ever met one set of triplets, all girls, and from what I remember two of them were identical and the other wasn't. The two identical girls were Nat@sha and Steph@nie and the third sister was Ellie, short for Eleanor, I think.
I'm a twin! My brother is named James, so...
Kathryn & James
Elizabeth (Liz) & William (Willy, now Will)
Megan & Melissa
Caitlin & CJ (I think his first name was Christopher)
...for some reason that's all the names I can remember of twins I went to school with, but I know there were lots more. They did a piece on it in our yearbook one year. I wish I had them here so I could look it up, but they're at my mom's house.
Edited to add: Amelia (Ame, pronounced like Amy) & Ashleigh - they were in my girl scout troupe.
I know plenty of twins and two sets of triplets
