Regarding Perry W. Fuller, I have long been trying to find out what happened to him after 1892. By chance, I came across a book at the library called Columbia Then and Now, which  was written in the 1929.

According to the author, P. W. Fuller left Columbia, moved to Georgia (most likely Meriwether County) and died there. The following passage may explain why in Alsey Fuller's will, he left Perry's share in a trust to Jones Calhoun Fuller for Perry's children to divide. Evidently as early as 1879 Perry was already mixed up in religion and was losing everything he had.

This is the passage from the book concerning Perry William Fuller.

'There was a man by the name of P. W. Fuller, who ran a hat and clothing store on Main street near where the State Office is. He was a member of the Methodist Church; had a good business and had the respect of his fellowmen. He got the notion in his head that the Baptists were right, and quit the Methodist Church. Then he got the notion that the Jews were right; that the Savior had never come, and then he took up the fool notion of Spiritualism and kept going from bad to worse until he lost everything--- his business, his friends, his self-respect, and the respect of his fellowmen-- going into the depths of degradation. Leaving here he went to Georgia and died."
