So undecided about names for my twin girls! Help please?

Please only serious, polite answers. Im having twins girls in may and Im still really undecided about names! Ive recently fallen in love with the name Avalie but I want both the girls names to start with the same letter and I cant think of any other A names that I just love. And Im also stuck on Tatum and Taylor but theyre just a little too masculine for me. My husband loves the name Teagan but we have a neice named that and we are around her alot so thats a no. So, Im wanting some adorable, girlish A names and some other unique names that start with the same letter. The middle names will be Rebecca and Patricia, they dont change. The surname is Markham. Also, our childrens names are: Madison, Alison, Bella, Brie, Cyra, Sara, Creed, Cadey, Effie and Masen, so dont suggest them. Five are adopted so hush about me having 10 children. Id love for the girls to have names that dont start with the same letters as any of our other children, but its not a must. I hope this is coherant! Thanks and God Bless(: <3Massie
