Jordan was born in Tattenbar, eldest son of Samuel Jordan, farmer, and was educated at the Mulnlburtlin National Primary School, as well as at the Portora Royal School in Enniskillen. He is buried in Aghavea Church of Ireland churchyard, situated about 3 miles outside the village of Maguiresbridge in County Fermanagh. A merchant by profession, he became a member of the Fermanagh Urban Council, the Enniskillen Board of Guardians, the Fermanagh C.C. and of the Joint Committee of the Asylum for Tyrone and Fermanagh. He was connected with Temperance and kindred movements for many years. He was a member of the Tenant's Association, the Land League, the Irish National League and the United Irish League, successively. In 1902 he became the first nationalist chairman of Fermanagh County Council. The local branch of the UIL in Enniskillen which was largely dominated by working-class members was disaffiliated after it criticised merchants who dominated nationalist politics in the town – notably Jeremiah Jordan and his successor, Patrick Crumley – for decorating shops with Union Jacks and subscribing to a military monument.
Political career
From 1865, Jordan supported the Liberal party in Enniskillen municipal and parliamentary elections against the dominant Cole Earl of Enniskillen and Crichton Earl of Erne interests. In the early 1870s he joined the Home Rule League of Isaac Butt and spoke alongside Butt at an Enniskillen meeting in 1873. In 1880 he joined the Land League and helped to secure extensive Protestant support for it in Fermanagh by arguing that it was a law-abiding body whose principal aim was to help Gladstone and Bright overcome resistance to further land reform. Most of this Protestant support died away after the 1881 Land Act and the agrarian violence of 1881–82. After the Kilmainham Treaty Jordan definitively committed himself to nationalism by joining the Irish National League. A Protestant Nationalist member of the Irish Parliamentary Party, Jordan was elected at the 1885 general election as MP for the Western division of County Clare. His only opponent was a Conservative, who won less than 4% of the votes. He was returned unopposed in 1886,. When the Irish Party split in 1891 over the leadership of Charles Stewart Parnell, Jordan sided with the majority Anti-Parnellite faction - he had been the first Nationalist MP to call for Parnell's resignation, partly because of his close association with the English Methodist spokesman Hugh Price Hughes. At the 1892 general election he did not stand again in West Clare, but in North Fermanagh, where he lost the seat to a Unionist candidate. However, the 1892 election in South Meath was voided after an electoral petition, and at the resulting by-election on 17 February 1893, Jordan won the seat in a close contest with the Parnellite candidate. At the next election, in July 1895, Jordan narrowly lost the South Meath seat to Parnell's older brother, John Howard Parnell. However, he had also stood in South Fermanagh, where he was elected with a comfortable majority. from 1895 to 1910. That constituency returned Jordan to Westminster in 1900, 1906 and January 1910. By then he was 80 years old, and after suffering a series of strokes he did not contest the December 1910 general election. He died a year later at High Street, Enniskillen, aged 81, according to some accounts, or 83, according to his death certificate.
