While you were digging into the Pricers, I was too, so I can add on to your pieces.
Yes, "Caroline" married a man named John JACK --26 April 1879, KS: Butler.They are in KS: Butler, Bruno twp., in 1880 Census with her daughter by Joseph Black and their infant son.From there they went to Story co., IA, where both died: John Jack died Aug 17 1911 Mary Jack died Oct 7 1928 Both are buried in Colo Cemetery, Story Co., IA.
Their son Robert (never married) is buried in same cemetery.Their daughter, Alta Mae, is also buried there. She married Nelson Perry in Story Co., IA in 1904.They apparently did not have any children.
I have a few more details on the above, if you wish.
I do not know what happened to Cora, the daughter of Joseph and Caroline.
Note that our subject is "Caroline" in 1860 and 1870 Censuses, and from then on out is either Mary C. or Mary.she was also Mary C. in the 1850 Census.
Thanks so much for this information.You certainly did produce it fast!
