1858 ~ ?
After Robert's father was widowed in 1852, he remarried to widow Nancy McCarty Artt. In the mid-1850s, they moved from Bracken Co.,KY, to Coles/Douglas Co., IL. It was there that Robert was born in 1858.
He was in the 1860 census of Douglas Co., IL, age 11/12 and born in Illinois. Also in the house was his older full sister, Georgia, his step-sister Sarah Arts, and four half-siblings. [Source: Douglas Co., IL, Census, 1860, Comargo Twp, household 487] His mother died in 1866.
He next showed up in the 1870 census, same county, but now in Tuscola Twp. where his still-widowed father had moved to the town of Tuscola. Robert was now age 10. At home was his full sister, Georgia, and two older step-siblings. [HH 210]
In 1871, Robert's father remarried to Amanda Rina, but they did not have additional children.
In 1885, Robert's father, William, died in Douglas Co., IL. I do not know what happened to Robert. He was not in the 1880 census of Illinois or any other state I have checked.
