I adore [name]Rory[/name], but I tend to like older/more vintage names and so I’m worried that it would clash with other names I like for future children (eg. [name]Henry[/name], [name]Felix[/name], [name]Clark[/name], [name]Jasper[/name], [name]Asa[/name], [name]Violet[/name], [name]Rose[/name], [name]Ada[/name], [name]Alice[/name]…)
I really love [name]Rory[/name] on a boy. ([name]Don[/name]'t like it all on a girl.) I think that [name]Rory[/name] is really cool and your other names, while vintage, also have a cool factor as well. No problems on sib set in my opinion.
I don’t think it’s a problem with the other names you like 
I think it does have the vintage appeal and fits well with the other names on your list!
[name]Rory[/name] sounds fine to me and I don’t see how it would clash with any future names (amazed by your forward planning BTW!). I think if you have 2 boys called [name]Rory[/name] and [name]Felix[/name], or a boy and girl called [name]Rory[/name] and [name]Alice[/name]/[name]Violet[/name]/[name]Rose[/name], then that would be fine
I think it works well! I’m biased as [name]Rory[/name] is in my top 2 names for a boy. But I like it because it has a really rich heritage and history.
I’m so happy to be seeing [name]Rory[/name] on people’s boy lists, it makes me pretty sad seeing it on girl lists because I don’t see how it can even be considered slightly feminine!
I think it fits well with the other short names on your list and I could totally see brothers named [name]Rory[/name] & [name]Felix[/name] or [name]Rory[/name] & [name]Jasper[/name], as well as brother and sister named [name]Rory[/name] & [name]Alice[/name].
