If you like Madison and Macy how about Maggie? I have a dog named Maggie and I like it cause it's easy to say...Ive got a Cabot address but I live about halfway between Cabot and Furlow.
Believe it or not Ive got Molly on my list.
My son has a Daisy now and Ive had beagles before named Sadie and Annie. I might use Annie again though cause I like that name.
I like Macy and Madison too but my grandaughter is Madison and I have a niece named Macy. I dont know if theyd take that as a compliment or not.
Peyton is a good name especially for the way you came up with it.
