Have you come across any information about an Elizabeth Truland who married an Alexander J. McCoy and moved from either New Hampshire or Vermont( with a small daughter, presumed to be Elizabeth McCoy Flanagan, oldest of two) to Illinois in approximately 1865?

I am desperately trying to locate family info and have only blank walls. She was my maternal ggmother, mother of my gmother, Mary McCoy, her younger daughter who died at 26 in or around city of Freeport, Stephenson County, Illinois.
