Spent some time this week covering the Crawfords--Ada Rippey's sister married Fredrick Swartz Crawford and had four children. He was a Presbyterian minister appearing in the 1898 directory of ministers. Mary was, I fervently hope, "Mary E Rippey" born in 1858, not the Mary Rippey born to George Orson Rippey in 1859.
Ada went to Monmouth College in Illinois. I wonder if and whether Mary went to college. Her first child, Ada Vere, is born in Ohio, indicating maybe that Crawford had a post there.
A sidenote--it seems the norm that when the husband died, the wife lived with a daughter or stayed on the farm with the son who was farming it. But in the case of Elizabeth Black, it seems neither happened. First there was no farm to inherit. (I write that then wonder--couldn't he have been farming as well as preaching, but I don't think that's reflected in the census data.) Joseph was moving in this time period, from NY to PA by way of Nebraska. Mary had her two sons in 93 and 94, right when Rev. John died. And Ada was in New York City, probably not an environment Elizabeth would like.
So the best I can tell, with the possibility of confusion over the Blacks, Elizabeth headed back to the family farm with her maiden sisters (3) and bachelor brother.
