Names that go with....?

I have two girls Harper Suzanne (Suzanne was my moms name) and Tucker Kathleen (Tucker is a family name after my father who also passed). And I have a son John Michael (he’s the 3rd). I’m looking for name ideas for girl or boy that would go along.

Other family names we like are Bruce, Leighton, Christopher

Names I like for a girl are Sawyer, Cooper, Ophelia

Any ideas are welcome!!
