Hawkey Family split btw East Coast & West

My name is Andrea Hawkey - I am 25 and live in New York.My father is Robert William Hawkey.Grandfather is Charles Hawkey.

I'm looking for information about my Grandfather, Charles.He was born in the US and married Gretta Grant in New Jersey.Charles was the youngest (by over 10 years) of about 7 children.Therefore, he was not close to his brothers and sister and I don't have their names.I hear that some of them moved to Northern California and may have settled and had families there.

Is there anyone out there with a link?
Thanks - very cool to know that this proud name spans the globe!
