One of the greatest friends of the Mormon church in Cane Creek who was not a member was
Three of the missionaries stayed at his house the night before the massacre. And on the day of the massacre it is likely he was still at his home, though he did help one of the surviving missionaries escape to Shady Grove. He met B. H. Roberts on his trip in disguise to retrieve the bodies of Gibbs and Berry. And it was to Tom only the Roberts revealed his true identity.
According to B. H. Roberts and W. L. Pinkerton he leaves Cane Creek after the massacre for Woburn, Illinois. Isaac’s grand father, Willis Dodson, moved there some 50 years earlier, so Isaac may have had family there. His family is described as a wife (Marthey J.) and a daughter (Elizabeth C.). Mrs Garrett had a half brother, William Lankford, who was a doctor. The Lankfords lived in the same census district as the Garretts.
At Woburn the trail runs cold. By the 1900 census, Tom disappears, probably having died from old age. Without the 1890 census, we cannot tell where he went. Although I have not made an exhaustive search, for now what happened to Tom Garrett after he left Tennessee remains a mystery.
