BEN F. CALDWELL.  The origin of the Caldwell family, of which our subject is a prominent descendant, can be traced back to the fourth generation in Ireland.  Thomas Caldwell, the great-grandfather, was born in the North of Ireland of Scotch Irish parents.  He married Miss Betsey Harris, a Welsh lady, and they decided to move to the New World where they would have a better opportunity of making for themselves and family a home.  They landed at Charleston, S.C., about 1760, remained there a short time, and then removed to Virginia, locating in Nansemond County.  There William Caldwell, the grandfather of our subject, was born December 15, 1779.  When he was but a youth his parents removed to Jessamine County, Ky., where they subsequently died at the home of their son.  The Hon. William Caldwell was a man of more than ordinary ability; while living in Kentucky he held several important positions of public trust, serving the county as Sheriff and representing it several terms in the State Legislature.  In Jessamine County, Ky., February 7, 1804, he was married to Nancy Robards, who was born in Goochland County, Va., September 24, 1782.  To this union came six children - George L., John, Jane R., Elizabeth, Charles H. and William, Jr., all of whom are now dead.  The Hon. William Caldwell removed to Carrollton, Greene County, Ill., in 1831, and near to Auburn, Sangamon County, in 1836.  After sojourning in the latter place several years he removed to the town of Curran, where he spent the remainder of his days, dying there August 1, 1844.  His widow survived until December 19, 1858.  When the Hon. Mr. Caldwell came to Curran he found no place for holding public worship near, and in order to afford temporary accommodations he constructed his residence in such a manner that it could be used for that purpose.  It consisted of a large central room with three others opening into it.  Plans were laid for the building of a church, but Mr. Caldwell did not live to see it built.  On his death bed he requested that when built it be called Bethel, which was done.  During the War of 1812 he was a Captain of a company from Jessamine County, Ky.  He was a man of ardent public spirit and after becoming a resident of this county he served one term in the Legislature with credit...
