Honest opinions - name to go with Lillan or William

[SleeplessInGarforth]

I'm preggers with DC2.
DC1 is called Rosalyn Laura (Laura being DH's grandmother).

Want to use a middle name from my family for this our (most likely final) DC.

Names to go with Lillian or William...

So far in my head I have:
Tamsin Lillian
Francesca Lillian
Sophia Lillian

Jonah William
Zachary William

Honest opinions and other suggestions please :)

I think they are all nice but my favourite girl's name is Francesca and Jonah for a boy

Thank you :)

Alexander William
Isaac William
Josiah William

Love Jonah William though!

Thank you :)
My grandad was John William so I thought Jonah William would be a nice way to remember him (he was an awesome chap who looked after me a lot when I was little and my parents split up blah blah blah).

My only worry is we're not religious and wasn't sure about choosing an obviously biblical name.

Francesca Lilian or Zachary William. They have the best 'ring' to them IMO.

would you consider Frances Lilian?
Francesca Lillian is a bit tongue twisty

Sophia or Zachary.

My dd is a Lilian, so I think it's a lovely name (personally prefer it with one L as that's how dh's gran spelled it and because she is mostly a Lily). She really likes having the family names (her middle name is from one of my grandmothers).

John William is a great name :) I don't like the bad luck connotations for Jonah, but Zachary William sounds good to me.

I'm not sure about your Lillian combinations, not sure the rhythm is quite right, but then it depends a bit on your surname too. I think they all sound better the other way around. dd tells me that's just my prejudice though, and Francesca Lillian is best.

Rosalyn and Francesca. Rosalyn and Zachary. Sounds good. I like Rosalyn :)

I love Jonah and although I know the bible story i don't relate it to religion or bad luck. I know a couple of awesome kids called Jonah. Sophia Lilian is my favorite of your girls.
How about Clara Lillian or Claudia Lillian?
