[name_f]Romilly[/name_f] is gorgeous!
[name_m]Not[/name_m] an [name_f]Aussie[/name_f], so I can’t speak to pronunciation, but here in the US it would be ROM-ih-lee. At least, that’s the only way I’ve ever heard it? I found this example of a [name_f]Brit[/name_f] saying it and it sounded pretty similar to me, as well: https://forvo.com/word/romilly/#fr
[name_f]Milly[/name_f] is cute, but [name_f]Romy[/name_f] in general has so much of my heart that I’m not sure I could consider anything else. I would love to meet a [name_f]Romilly[/name_f] nn [name_f]Romy[/name_f]!
I only know of one person who used [name_f]Romilly[/name_f] - and her older daughter was named [name_f]Waverly[/name_f]. [name_f]She[/name_f] almost used [name_f]Bryony[/name_f] instead of [name_f]Romilly[/name_f], so the 3 of them feel like a match made in heaven to me! I’m also majorly crushing on [name_f]Lyra[/name_f] [name_f]Romilly[/name_f] lately so I also really love the idea of [name_f]Lyra[/name_f] and [name_f]Romilly[/name_f] as sisters too.
Good luck!
