What would you name a sister to me?

My mom is not pregnant and I highly doubt (more like know) she ever will be, but I’m really curious to see what names you think would work with my name since it’s so unusual (and not a name).

My name is Chatelaine (pronounced shat-elaine). My parents found it when going through the dictionary. It’s [name_m]French[/name_m] and it means lady of the castle/woman in charge of a large house/keeper of the keys. They chose it because it’s unusual (more like unheard of as a name), it’s [name_m]French[/name_m] (they really like [name_m]French[/name_m] names, but that’s not a requirement for this exercise), they loved the sound, and they liked the meaning. I’m curious because it seems so difficult to match and I wonder what suggestions all you Berries would give if my mom was currently looking for them.

I realise this is somewhat of a strange post (and probably pointless), so extra thank yous all around!

[name_f]Chantelle[/name_f] might be too close but that would be beautiful.

[name_f]Cecily[/name_f]
[name_f]Anneliese[/name_f]
[name_f]Rosaline[/name_f]
[name_f]Lucienne[/name_f]
[name_f]Viviette[/name_f]
[name_f]Leonie[/name_f]
[name_f]Primrose[/name_f]
[name_f]Marguerite[/name_f]
[name_f]Ottilie[/name_f]
[name_f]Appoline[/name_f]
[name_f]Hermione[/name_f]
[name_f]Liliane[/name_f]
[name_f]Marceline[/name_f]
[name_f]Eulalie[/name_f]

My first thought is [name_f]Enjoli[/name_f]

My first thought was Chatelaine and [name_f]Rosamund[/name_f]!

Here are some others;
[name_f]Mirabelle[/name_f]
[name_f]Alexandria[/name_f]
[name_f]Annabella[/name_f]
[name_f]Arabella[/name_f]
[name_f]Emmeline[/name_f]
[name_f]Marguerite[/name_f]
[name_f]Evangeline[/name_f]
[name_f]Ophelia[/name_f]
[name_f]Ophelie[/name_f]
[name_f]Camille[/name_f]
[name_f]Aurelie[/name_f]
[name_f]Christabel[/name_f]
[name_f]Christiana[/name_f]
[name_f]Amelie[/name_f]
[name_f]Genevieve[/name_f]
[name_f]Imogen[/name_f]
[name_f]Lavinia[/name_f]

Something elaborate and romantic with a medieval feel, like [name_f]Melisande[/name_f], [name_f]Guinevere[/name_f], Ludivine or [name_f]Esclarmonde[/name_f]!

[name_f]Angelique[/name_f] or [name_f]Lorelei[/name_f]

I came across 2 names recently that came to mind as sibsets for Chatelaine: Elexina or Candelaria.

Thank you everyone. This is so interesting!
