In the 1860s a personal tragedy occurred: In the early 1850s, her son Joseph had gone to California to search for gold together with his uncle John. Later the two had continued on to Australia. John S. Jacobs later went to England, while Joseph stayed in Australia. Some time later, no more letters reached Jacobs from Australia. Using her connections to Australian clergymen, Child had an appeal on behalf of her friend read in Australian churches, but to no avail. Jacobs never again heard of her son.
