Naming child after family.

So I want to name our child after my grandma if it's a girl my grandmother raised me for a while and I was with her in the hospital for two weeks watching her die from cancer. But my dilemma is her name. We don't like it... Unia Elaine.

Ive never heard the name unia for anyone else. And Elaine is a family name my aunts and sister and a few cousins are named Elaine mainly their middle name. So it doesn't see so special or unique to my grandma since my family ran off with it. And I suggested to my husband giving the middle name petunia to kind of add to unia but he hates flower names and would rather name her Elaine :( so what would you choose? (McGlade is our last name)
