Eleanor's grave has not been located. The graveyard Hugh is buried in wasn't founded until 20 years after her death. She is probably buried in old Waxhaw Presb. Cemetery, though no marked grave can be found.
Irene Amato writes "Hugh and Eleanor lived in the old Fortee Place on the Catawba River, where Waxhaw Creek enters and in the area where William Nutt, her father, had his large plantation. He died on his plantation which lay along Cane Creek. Their
home was a short distance southeast of where the present North Carolina highway #16 crosses Cane Creek."
A letter which shows what an outstanding woman Eleanor was, was written 7 May 1902, by J.G. McCain of Champagnolle, Arkansas. One excerpt reads: "The wife of Hugh McCain had great qualities of heart and mind. She was one of the old time doctors and during the Revolutionary War spent a great deal of time waiting on the sick and wounded. A tragedy was malted in her house which illustrates to some extent the terrible times in which she lived.
A Tory was sick in her home and she nursed and doctored him through the serious illness. When he was well, to show his appreciation and gratitude, he stole the fine horse which she had been riding for years on errands of mercy. Soon he was taken ill again and went to her house for treatment. She forgave him and did all she could for him. But an old Captain rebel, who was said to be a desperado, hearing that he had gone back to her house after treating her so badly, went to her home and walked into the room where the man was lying, ordered him to sit up and open his bosom, which the poor fellow did. The rebel ran a sword through him and killed him in bed."
There are those that argue that Jane Pickens Davis was the mother of Hugh's children. Since his first child was born in 1753, that would have made Jane only 12 years old - very unlikely.
Also, Hugh's 8th son was named Joseph Nutt McCain, which adds to the evidence that Eleanor was their mother. Also, Hugh's sons have the names of Eleanor's brothers, John, William & Andrew.
