I like [name_f]Martha[/name_f] best with [name_f]Clara[/name_f] and [name_f]Ella[/name_f] – it’s 2 syllables and ends with an “a”, but it has a distinctly different sound
I love [name_f]Flora[/name_f], but it has much the same sound as [name_f]Clara[/name_f]
I also love [name_f]Anna[/name_f], as long as [name_f]Anna[/name_f] and [name_f]Ella[/name_f] doesn’t start to sound a bit too Frozen to you!
If you decide to forgo an “a” ending, I think [name_f]Margot[/name_f] sounds great with this sibset, too!
