Seems we might have another Mary "Polly" Yow in your case. The information I assembled on Mary "Polly" Chrisco Yow came from the Yow Family Files, Randolph Room, Randolph County, N.C. Mary Chrisco married Emmanuel Yow and they had seven children: Martha "Patsy(1814),Molcy (1815),William (1820), John H.(1824),Elizabeth(1825),James(1828) and Andrew Jackson (1833)Martha and Molcy married Needham brothers James and Elijah. Elijah was my great great grandfather and lived in the Sheffield Township, Moore County, but the family had earlier lived in the Brower's Township, Randolph County. These two townships have common boundaries and my Elijah and his wife Molcy are buried at Needham's Grove Baptist Church cemetery in Moore County. With your dates we seem to be looking at Polly Yow's possibly a generation apart.
