Polly Harp was married to my g g grandfather, Pleasant Elijah Harp. I got her name off of my g grandfather's death certificate. His name was Pleasant "Pless" Elijah Harp, Jr. He was married to Eliza Jane Horne. He and Liza are buried at Hebron Methodist Church Cemetery, McBee, SC.
I'm not sure who Eliz is unless it was short for Elijah. I have been unable to find Polly's maiden name. Where did you find that she and Eliz are in John Miles household. I wonder if John Miles is a relative of her's as I have found no connection to any Miles on the Harp lineage.
All of my Harp family is from Chesterfield, SC and Anson County, NC. I have more info if you wish to share please e-mail to CMoodyM@peoplepc.com
Look forward to hearing from you.
