I am a descendant of Richard Nelson Allcock also.According to my records Richard Nelson married Mrs. Sarah White Murphy in North Carolina and they had three sons, Counsel, Durin, and James.My line is through James who married Mary "Polly" Housman Dec. 18, 1811. The children I have listed for them are: 1. Jeremiah Murphy Allcock - born 1814 2. Wilkinson Allcock - born 1815 3. Mathilda Allcock - born 1819 4. T. D. Allcock - born 1823 5. Richard Nelson Allcock - born 1826 6. Catherine Allcock - born 1827 7. William Oliver Allcock - Born 1827 8. Sarah Allcock - born 1831 9. John Reanaldo Allcock - born 1834
William Oliver Allcock is my maternal great-great-grandfather.
I have considerable information about James' line and some on Counsel and Durin. I will be happy to exchange any information.
