I think how it's said in English is "My family has 4 people in it; my dad, my mom, my older brother, and me," and in Japanse, I know how to say that. What I don't know is how I'm supposed to connect the two sentences together. Do they have a specific phrase or particle for that, or do they just use :/; like in English?

This is the best I got: Ex. 家族は七人;父と母と兄と私です。
