ASHCRAFT FAMILY OF INDIANA

I have just begun an interest in my family geneology and therefore I do not have much information.However, my father has a family tree streching over many generations of Ashcrafts.He even has a will from his great-great-great grandfather that lived in Virginia.If anyone can give me some research tips, I would greatly appreciate it.Also, if anyone is a decendent of the Ashcraft Family from Indiana I would be interested to know how.
