Jacob Barrett was born in the State of Virginia November 25, 1819. When he was some four or five years of age his parents moved to Washington County, Indiana. Here he spent his boyhood, and was married in 1838 to Mary Crunk. Of this union two daughters were born, one of whom survives the father. Mrs. Mary Barrett died October 17, 1843.

Mr. Barrett enlisted in the survive (service) of his country during the civil war and served until peace was declared.
Mr. Barrett moved with him from Indiana to Illinois, where they resided several years, coming to Nebraska in 1880 and taking up their residence. Here he continued to make his home until his death. Some thirteen years ago he had the misfortune to suffer an accident which resulted in a fractured hip. This confined him to his home and couch for a long time, and he never completely recovered from its effects. He was, however, able to get about some afterwards, but during the last few years he had been getting feebler in health, and since last fall he had not been able to get around at all. Of late he had suffered a great deal and at last he has laid his weary frame to rest the rest of the just.
When but a child Mr. Barrett became a member of the Methodist Episcopal Church. The first local church to which he belonged met in his childhood home. During four score years he lived the Christian life and walked with his Maker. Whether in labor for Christ and the church, or in suffering he has convinced people both in the church and outside of the reality of his religion. His benign countenance, his words of faith and courage and his earnest work all spoke of the Christ who resigned within.
He leave(s) behind his aged widow, four sons, and four daughters, with many grandchildren and great grandchildren and hosts of friends who will miss him and yet who sorrow not as those who have no hope. The memory of the just is blessed.
