Baby names?

I have two daughters: Autumn Jo (Jo after me) and Winter Lily (Lily after Harry Potter's mom). If we have another girl, we will name her Summer. But we have zero middle name options that mean anything.

Summer Rose is pretty, but has no meaning. All the women in our family have terrible names. Haha. My grandmothers were Nan and Viola. My mom is Melissa. I will never name my child after my MIL. My husband's step mother is named Phyllis.

My sister's middle name is Leigh. I think Summer Leigh is pretty. My husband doesn't want to name our daughter after my sister, even though she will be godmother. My husband thinks naming her Summer Samantha after me is pretty. I hate it. Samantha is never meant to be a middle name.

Praying it might be a boy so we can avoid this. Haha. 😅
