It does appear that the Hugh Yourd who was born Jan 21, 1835, Sandy Creek, Alleghenty, Pennsylvania and died April 12, 1912, Keener, Boone, Arkansas was married and living in Perry County, Illinois 1850-1860. However I can't find him on the Census.
I'd contact the Perry County Genealogical Research Library & Archive Center, https://perrycountyhistoricalsociety.wordpress.com/
who has most county records 1821-1921 and county marriage records 1825-1937. Maybe they can find Hugh and his first wife. Successful Searching!
