Jami

We want to incorporate his grandfather's name Ray into either gender (we are still early and don't know what we are having) and possibly my grandfather's name of James but I wanted to mix it up to Jamison but he's not budging on it. And we can't decide on a girl name to go with Rae for a girl. What do y'all think..... James Ray or Jamison Ray? And help with ideas for a girl.....(I wanted Charlotte but he hates the name so it's a no go)

Would it be wrong to call baby boy Jamie.. if sibling is named aimee..some ppl say no some say ya..unsure
