I have a copy of the abstract for Azaniah Langley's estate record from Estate Records of Edgecombe County, NC, 1730- 1820 by Joseph W. Watson. According to the abstract, Azaniah Langley's heirs were Dorcas Langley, Isaiah Langley, Shadrach Langley, Rhody Page wife of Willm. Page, Jehua Langley, Susanna Page wife of Milch'd Page, Trefaney Langley, and Jane Langley.
I was interested in the husband of Sarah Langley as Sarah is my husband's ancestor's sister. She was a buyer at Azaniah's estate sale and probably married to one of his sons. I have no info on William Shadrach or Moses Langley.
