Middle name help

Monica • I`m a 30 year old military wife and mother to our 9 year old son, Rylan and daughter, Maci who is 4.
Last name is Valentin (Val-en-teen). Lillian would be after my MIL, Caroline would be after my Aunt, AnnaLee would be after my Grandma and dad. My husband likes Lillian best but I can't decide because my aunt, dad, and gma all mean so much to me. And our son is already named after his brother. So I feel it's my turn lol please help. Which flows the best?
