Middle names! Can't think of anything...

[LAbaby]

I have quite a few ideas for first names, but can't even begin to think of a middle name. We don't know the sex of our baby either, which doesn't help!
I am keen to avoid a 'filler' middle name - mine is Jane - I was born in the 80s and it seemed every second girl at my school had the middle name Jane, Elizabeth or Louise.
Today the equivalent seems to be Grace, Rose or May/Mae. I love those names and my grandmothers were Rose and May, but as a child I always wished my mum had picked something a bit less popular, and don't want to do the same just because it is easier for me.
BUT have no idea what else to choose.
All the girls first names I have chosen end in an 'a' sound - so don't want that for the middle names.
And have NO ideas for boys!!
Any suggestions welcome.

Any other family names? I think middle names are a great way to use them. All our middle name choices were traditional family names, e.g. Thomas, James, William etc, because first names we chose were much less popular, and some a bit unusual. Would you tell your first name ideas so we can think how they sound together? And what letter does your last name start with?
