Larry Lovett of California with Southern Roots

Larry Lovett is descended from David Lovett (b. 1782 probably in North Carolina).David Lovett's descendents lived in Alabama, Mississippi, Texas, Arkansas and eventually California.
In addition to Lovett, I am searching for Harges, Mills, Cannon, Phelps and McCrory surnames.I am particularly interested in information regarding John Porter Harges b. 1870 probably in Kentucky.
