The sibset is kinda meh to me - the names are pretty distinct from one another in origin, last syllable aside.
Ginger is fine as a nickname,
Jasper is fine.
Juniper is okay.
Winter is not my style, and
Jupiter is very much not my style.
We had family friends when I was growing up where every one of their five kids' names ended with -an or -in. Didn't love the names, but they were fine for the time and actually fit well together (
Justin,
Ryan,
Megan,
Nathan,
Kevin).
Andrew
