My grandmother’s fn was [name]Betty[/name], I would love to honor her and thought about using [name]Elizabeth[/name] to honor her…would this work? It would be as a middle name, [name]Rose[/name] [name]Elizabeth[/name]. The only problem becomes is that I also want to honor my mom…her first name is [name]Beverly[/name] and her middle name is [name]Jo[/name]. So assuming I have twins, and they were both girls, what would you suggest as a way to honor my mom and a sister to [name]Rose[/name] [name]Elizabeth[/name].
Also what are your thoughts on [name]Rose[/name] [name]Elizabeth[/name]? (If we had a son his name would be [name]Charles[/name] [name]Martin[/name]-[name]Charles[/name] after a friend of my husband’s that passed away and [name]Martin[/name] is my maiden name). Thanks!
[name]Hi[/name]! [name]Rose[/name] [name]Elizabeth[/name] is actually my favorite name in the world, and it’s what I plan to name my daughter someday. 
I think it’s a gorgeous name, and as [name]Betty[/name] is a nickname of [name]Elizabeth[/name], it’s a perfect choice for you.
For [name]Rose[/name]'s potential twin sister, I think your mom and grandma could be honored with [name]Josephine[/name] [name]Bevin[/name] (a Scottish name).
Best wishes!
Or [name]Bettina[/name]? [name]Rose[/name] [name]Bettina[/name]
