Oliver holds the top spot in Montana's 2025 boys' names, with 62 babies, ahead of Henry (58) and William (52).
The top of the list has a classic feel: Theodore and Hudson tie at 45 births, with James and Liam still close by.
The sharpest risers are Elliott (+160), Callum (+135), Christopher (+116) and Alexander (+111), while August (-43), Ryder (-38) and Mason (-30) fall furthest.
Short surname-style choices like Hayes, Brooks and Tate sit beside vintage revivals such as Arthur and Calvin, while River and Jasper add a nature-leaning note.
