I have several ideas for her in mind, but i’m not sure if they flow well.
[name_f]Rose[/name_f] [name_f]Heather[/name_f] (Heather was my grans name)
[name_f]Rose[/name_f] [name_f]Irene[/name_f]
[name_f]Rose[/name_f] [name_f]Ophelia[/name_f]
[name_f]Rose[/name_f] [name_f]Genevieve[/name_f]
[name_f]Rose[/name_f] [name_f]Josephine[/name_f] (My other grans mn)
Any opinions appreciated 
[name_f]Rose[/name_f] [name_f]Josephine[/name_f] and [name_f]Rose[/name_f] [name_f]Genevieve[/name_f] are lovely!!
Firstly [name_f]Rose[/name_f] is beautiful 
[name_f]My[/name_f] thoughts on your list
[name_f]Rose[/name_f] [name_f]Heather[/name_f] ~ I love that [name_f]Heather[/name_f] is a family name she is gorgeous with lovely imagery attached. Another bonus is that she’s a family name which is of course wonderful. I just think that [name_f]Rose[/name_f] [name_f]Heather[/name_f] has an odd flow. Could you have two middle names? [name_f]Rose[/name_f] [name_f]Josephine[/name_f] [name_f]Heather[/name_f] could be nice and honours both grandmothers.

[name_f]Rose[/name_f] [name_f]Irene[/name_f] ~ I think [name_f]Irene[/name_f] sounds a bit stunted with [name_f]Rose[/name_f] personally I prefer [name_f]Rose[/name_f] with a longer name or maybe a shorter name ending in an ‘a’ sound.

Love Rose Josephine!
[name_f]Ophelia[/name_f] is my favourite middle (and the one I’d choose) but my second favourite, and the best in terms of flow in my opinion is [name_f]Rose[/name_f] [name_f]Genevieve[/name_f]. [name_f]Rose[/name_f] is a lovely name!
[name_f]Welcome[/name_f]!
I think all the names on your list work well in different ways. And I love [name_f]Rose[/name_f] as a first name!
[name_f]Heather[/name_f] and [name_f]Josephine[/name_f] have the lovely advantage of family connections, and I like the unexpectedness of [name_f]Heather[/name_f]. I don’t always like 2 flower names together, but this one kind of appeals to me. I love the vintage chic and unexpectedness of [name_f]Irene[/name_f] as well.
[name_f]Genevieve[/name_f] is my favourite of the names, and just for the sounds and name appeal this is the one I would choose… but I do think family connections make a strong pull towards the choice of either [name_f]Heather[/name_f] or [name_f]Josephine[/name_f].
[name_f]Rose[/name_f] [name_f]Genevieve[/name_f] is BEAUTIFUL!!!
Yet, the significance of [name_f]Josephine[/name_f] would like pull me in that direction. [name_f]Rose[/name_f] [name_f]Josephine[/name_f] is very lovely as well!
