The History of Hendricks County (Chicago: Interstate Publishing, 1885)--Guilford Township, page 627
John R. Weer, a prominent and enterprising farmer of Guilford Township, was born in Warren County, Ohio, Feb. 22, 1831, a son of Elijah and Margaret (Cox) Weer, natives of North Carolina, who settled in Washington Township, this county, in 1832, where the father died in 1850, and the mother in 1865. They were active members of the Christian church, he serving as Elder several years. Their children were ten in number—Emily, Samuel, John R., David, Hiram, Harris, Julia, Elizabeth, Martha and Amanda J. John R. Weer was reared on his father's farm, in Washington Township. After the death of his father he took charge of the farm, and after his marriage bought the interests of the rest of the heirs. In addition to the 120 acres entered by his father, he now owns 215 acres which makes a fine farm of 335 acres. He has made a specialty of stock-raising and in 1884 fattened 121 head of Poland-China hogs. He has been one of the most successful horse-breeders in the township. In 1882 he moved to Plainfield, giving the management of his farm to his son-in-law, George Carr. He was married in 1853 to Emma Gunn, daughter of John and Lydia Gunn. They have three children—Martha A., wife of Theodore Walton; Lydia, wife of George Carr, and Ernest E. Mr. and Mrs. Weer are members of the Christian church, of which he is an Elder and Trustee.
