Philip Jonah and Patricia Elaine or Robert Preston and Rebecca Elaine? ?

Im still undecided! I adore all the names and just cannot decide. Before you say Patricia will be called Pat or Patsy in school, she will be called Pippa from the moment shes born if we choose that. The name Patricia was the name of the doctor that delivered me and I have always loved the name and she recently died so I wanted to use it too. But Rebecca is my mothers name and shes just been diagnosed with cancer. So I want to honor her. As you can see, Im at a crossroads here. The boys name stay although Im not sure about Roberts middle name being Preston. Any suggestions? As for other nicknames, Rebecca would be Becca, Robert would be Bobby and Philip would probably stay Philip. Any help would be gratefully welcomed but please be nice. Im in a pretty fragile state of mind right now, on top of being busy with my brood of kiddos, work and everyone in my family getting sick and/or dying. Please dont add to it by being mean about something as simple as a possible baby name. Thanks and God Bless(:
