According to marriage records, Elizabeth Pendley Nelson was a daughter of William Penley and Mary Ferguson.

Below is her obituary, written well over 100 years ago:

"To the Editor of the Lenoir Topic:

After a brief illness of typhoid fever, and a chronic disease of many years standing, our dear mother, Mrs. Elizabeth Nelson, wife of John Nelson, quietly fell asleep in Jesus at her home near Patterson, N.C., August the 20th, 1880, in the sixty-fifth year of her age.

We are thus called to mourn the irreparable loss of a dear, devoted, Christian mother, whose material [maternal?] interest in the spiritual as well as the temporal welfare of her children was ever unceasing. Indeed, this charitable interest was not confined to her family alone, but extended to all with whom she had to do.

Others may have had mothers of greater worldly advantages, but no mother ever bequeathed to her family a richer legacy of love and deep devotion than did ours.

She joined the Baptist Church years ago, and lived a consistent member of the same till the year 1878, when a belief in the doctrines peculiar to the Second Advent people was made a bar of church fellowship. She then quietly withdrew her membership, and had not again attached herself to any Christian body.

She died in the full exercise of a gospel faith, leaving behind her the blessed testimony that she "had long loved her Saviour, that she was at perfect peace with Him, and was willing and ready to meet Him." Mother was fond of reading the Scriptures, and she had an abiding faith in their precious promises, and when death claimed her as his victim, she peacefully fell asleep, believing that when the great Lifegiver comes He will raise her to an endless life, and clothe her in the spotless robes of a glorious immortality.

who have no hope. For if we believe that Jesus died and rose again, even so them also which sleep in Jesus will God bring with Him. Wherefore comfort one another with these words."
