Middle Name Help?

We are stuck between 2 very meaningful middle names for our baby girl, Jean (my SO's grandmothers middle name whom is like a mother to him or Lynn (my SO's father's middle who was killed in a car crash a year ago). We are leaning more towards Lynn at the moment, the only question is our last name is Lucas, so will the 2 L names collide with each other. I love the way her first name and Lynn sound together but I'm afraid that Lynn Lucas together sounds kind of weird with the 2 L's..
