Regarding Jesse Shipton, born 1800 who married Julia Davis, he definitely did remarry, to Rosanna Hill. Their marriage can be found in Pike County, Illinois, 3 Jan 1838. One child, Isabella M. Shipton b. 1840.
Rosanna Hill Shipton went on to marry again in 1848 to John Gibson, born 16 Jun 1799 New York. This family settled in Clayton County, Iowa. John and Rosanna Gibson had six children there. One of these children, Jennie Gibson b. 27 Aug 1859, was the 3rd wife of Jasper Shipton b. 25 Apr 1841. Interesting too is that one of John Gibson's sons from a previous marriage, William Gibson b. 1838/1839, married Lucinda Gibson b. 14 Feb 1847. Both Lucinda and Jasper Shipton were children of Phillip Shipton and Lucinda Holcombe. Phillip Shipton was the brother of Jesse Shipton.
