In 1860, Prudence Henry Pointer was on the census in Ohio with her (believed to be) brother-in-law's family:

According to the 1850 Census there was also a son, William b. c. 1847 to William & Prudence who apparently died between 1850 & 1860 and a daughter Samantha who does not appear on the 1860 census either.

Note that Sarah J. was born in 1845, not in 1863 as you have mentioned.The census records are consistent in 1850 & 1860.The date of death that I show for her is in 1905 in Welston, OK.
