" On Wednesday evening, Jan 20th, Miss Adelaide L Avery, one of the oldest and most highly esteemed residents of Morganton, passed away quietly to her rest after a long and trying illness, which for the last six months, entirely confined her to bed.
She was the granddaughter of Col Waightstill Avery of Revolutionary fame, and the eldest daughter of Col Isaac Avery and Harriet Erwin, and was born at their home, Swan Ponds, Dec 20, 1822. But, although in her seventy fifth year, her great mental and social activities, as well as the natural vivacity of her temperament always made her appear much younger.
Ever personally interested in all that was likely to promote the progress and welfare of the community in which she lived, kind, generous and just in all her dealings, her death must long be felt as a general loss.
She was an earnest Christian, delved to the church of which she was a member, and ever ready to do her part in the Master’s work. Her bright, genial nature gained her many warm friends, but only those who knew her best could fully appreciate the worth of a character in which the most striking traits were a sincerity incapable of compromise and the most conscientious faithfulness to duty. Of her truly might it be said. “Well done good and faithful servant, enter thou into the joy of thy Lord”
“Another dear one taken
A little sooner house
The Savior marked her failing strength
And gently whispered, come.

How faithful she served Him,
The Master knoweth best,
Her work was done - In tender love
He bade His servant rest.

Ours all the loss and sorrow
Hers the eternal gain,
We would not have her linger here
In weakness and in pain.

Bur sorely we shall miss her,
And feel each day anew
No other ever can fill her place
So kindly, good and true. “
~~ A FRIEND"
