Hardey, Leo Carl, who is engaged in farming upon an extensive scale, is one of the leading agriculturalists of Fountain Green Township.  He was born in this township, June 21, 1882, a son of William Michael and Maria (Tallis) Hardey, the former of whom was born [in] Maryville, Union County, Ky., September 29, 1831, and the latter was born in Kilkenny, Ireland, December 24, 1849.

The paternal grandparents were Ira and Mary (Rhiley) Hardey, the former of whom was of English descent.  They came to Fountain Green Township in 1835, and he died there in his ninety-ninth year.

The maternal grandparents were William and Catherine (Ford) Tallis, the former of whom was born in Ireland in 1819, a son of John and Mary (Barnes) Tallis.

William Tallis was reared in Ireland, where he learned the shoemaking trade.  Leaving Ireland in 1859, he came to the United States, and after spending about a year in Ulster County, N. Y., he came west to St. Louis, Mo., soon thereafter securing employment on the construction of the Alton and Springfield Railroad.  Six months later he was placed in charge of a construction gang on the Great Western Railroad.  Fifteen months later he left that road to go with the Northern Cross Railroad carrying out the contract of Silas Roe, and remained with that road for eleven years.  He then purchased a farm in McDonough County, Ill., comprising 175 acres in Lamoine Township, adding to it until he had 267 acres, of which fifty-eight acres were in Lamoine Township, and the balance in Tennessee Township.  He wife's parents were Robert and Catherine (Ward) Ford, who died in Ireland.  Mrs. Tallis died November 10, 1903, and Mr. Tallis died January 15, 1907.

The children of William Michael and Maria (Tallis) Hardey were as follows: William, who lives at Minneapols [sic], Minn.; Evelyn, who is Mrs. Thomas Bowman of Rygate, Mont.; Joseph, who is on the home farm; Alice, who is Mrs. William Doran of Macomb, Ill.; and Earl, and Blanche and Leo Carl, who are all on the home farm.

The brothers, Joseph, Earl and Leo Carl, conduct the homestead of 320 acres of land on sections 36 and 25, Fountain Green Township, and the Tallis homestead in Tennessee Township, McDonough County, Ill., of 173 acres, carrying on general farming and stockraising.  The farm in Fountain Green Township is named The Pioneer Stock Farm.  The sister, Blanche, keeps house for her brothers.

Leo Carl Hardey attended the district schools, while William Hardey was graduated from St. Francis College of Quincy, Ill., and the sisters, Evelyn and Blanche, attended St. Mary's Academy at Nauvoo, Ill.  They all belong to the Catholic Mission of Tennessee Township.

In politics the brothers are Democrats, and they belong to Gabrault Council, K. of C., at Macomb, Ill., and Earl is also a member of the Elks.  Miss Blanche belongs to the Household Science Club of her township.  They are all very representative people of this section, and are held in the highest esteem by all who know them.
