Baby name help?!?!***?

My sister has a 3 year old son Adam James. James is After his grandfather and she likes the fact that they can call him AJ when hes older. Now shes on baby # 2 and is stuck between Connor Joel and Parker Joel. Joel is after the other grandfather so its a must in the name and she likes the CJ better than PJ but likes Parker because its the babys fathers middle name but then we get into well you named one after his dad and not the other.... not much more time to decide on a name shes due june 4th
