Special abandonded kitten names? Please help?

A few weeks ago my neighbors left a pregnant calico cat in their foreclosed home and moved out. When she had the kittens, we went in and got them. They are about 3-4 weeks old now and there are three girls and two boys. I need names for all of them. I am hoping we can find some symbolic names relating to being abandoned or the name of our street, Hummingbird. The girls are calico and greyish. the boys are black and white, and all grey. Thanks!
