Are matching names weird?

All of my mom's sister's names end with "ynne". Their names are Gracelynne, Kathrynne, Laurynne, Jordynne, and Erynne. Then my mom's name's Elizabeth and her other sister is named Lindsey. And my sisters are triplets, and their names are Emma Ella and AnnaSofia. We were going to name them Emma Ella and Anna, but we thought that was too matchy. SO my question is, is it weird to have kinda of themed names?
