Francis married a Charles Dougherty but I have no documentation for that marriage and there are many Charles Dougherty's in NY at the time.
What happened to Clarinda?
I do find a Clarinda Every or Evey in Middletown, Delaware County, age 26, on the 1870 census. Could that be Clarinda Oliver? I don't know. If it is, she and her family disappear again as of the 1880 census.
Let me know if you find her anywhere.
