Following from the Upswing Girls' Names in England and Wales, here is the picture for the boys.
Noticeably, the girls' names, on the whole, had a much steeper upward curve than their masculine counterparts. These boys' names, in general, are taking longer to rise and have a bumpier, more gradual upward curve, often with intermittent plateauing.
Going against this grain, some noticeable spikes can be seen, such as with Riley, Arthur, Jenson, Tommy and Frankie.

Similarly, names below the Top 100 also are a little bumpier on their upward path in popularity. Nevertheless they are all progressively rising.
Upswing Names below the Top 100:
Despite his previous reputation as a Cockney bad-boy, diminutive Ronnie is currently in vogue.
Back in 1996, 66 boys (#352) were called Ronnie in E&W. After a few ups, downs and plateaus, Ronnie managed to garner 599 births (#105) in 2012, over a hundred more than the previous peak of 491 babies in 2008.
Fellow, R- diminutive (and, coincidentally, the other Kray twin) Reggie is also rising behind. Only 16 (#898) babies were named Reggie in 1996. It reached triple figures (110) in 2005, and by 2012 there was a swelling 398 births, ranking #450.
Alternative Reginald-diminutive Rex is also enjoying rising usage. From 4 births (#2425) in 1999 to 88 births (#450) in 2012.
