Do My Sister & I's Names Go Together...

English (22)
[name]Madison[/name] (20)
[name]Tristan[/name] (16)

I’d definitely say so! English and [name]Madison[/name] fall into the surnames-on-girls category, and while [name]Tristan[/name] isn’t a surname, its membership to the “boys-names-on-girls” club is right in line with the masculine surnames. Your parents did a good job!
