Are these names too similar?

[jamesao]

Seren and Seraphina?

I would say so but both lovely in their own right!

For sisters? Yes I think so. Lovely names though.

Yes I think so.

such a shame :(

No, I think just because they start with the same letters and have a similar sound they do have different meanings at the end of the day, I guess what I'm saying is if you love them use them and don't worry what others think.

No, I would go with it, beautiful names.

Just go with it OP.
Josephine and Joanna
Caroline and Cara
Christina and Chrystal
Eleanor and Eloise
I know them all, don't spoil it for yourself.
It's not a shame, you've made a great choice. 😄

Yes.
Instead of Seren, you could try:
Serenity
Stella
Serena

Instead of Seraphina, what about:
Josefina
Edina
Nina

For siblings yes.

For cousins or friends no.

I think they are fine for siblings. Lovely names.

Yes, too matchy for siblings. No problem for cousins though I think.

As a pp mentioned them - I think Serena and Seraphina, or Serenity and Seraphina have the same issue!

I think they are too similar for sisters yes.
