Kegley Family Genealogy Forum
I don't know that he was the one who actually changed it but he ended up in Iowa as John Cagley. I connected with a genforum board there in Chickasaw County, who descended from John, and the lady with whom I was communicating knew he had left Virginia, homesteaded in Johnson County, IN, where my ancestors stayed and I was born, and then moved on to homestead again in Iowa, which is where he died. He was evidently a wealthy man at the time he arrived in Iowa.
I will find the connection and send it, but I think it was by going into www.usgenweb.com and then clicking on Iowa and then Chickasaw County, and looking for Cagley. You will find all sorts of connections there. There is a Cagley family cemetery in Nashua (?) Iowa and some place called The Brown Church, where there is a Cagley Family Book from which a lot of this information came.
