I too have hit a "brick wall" in my Case family. The following members
are buried at the cemetery in Merrillville, Lake County, Indiana:
Benjamin, son of David and Datey Case b. June 14, 1829 in NY, d. Sept.
15, 1918; Datey Mayo Case b. Nov. 9, 1794 in PA d. Sept. 10, 1881, wife
of David L. Case (I don't know where David died, but he was apparently
born in Delaware abt. 1794.); Elisha Mayo Case, son of David and Datey
Case b. July 28, 1834 d. Aug. 19, 1904; Eliza Jane 1856-1921 (possibly
the wife of a William Case), Maria A., daughter of David and Datey Case
b. March 5, 1836 d. June 30, 1883; Rebecca Hough Case, wife of Elisha
Mayo Case d. Aug. 17, 1863; Caroline Case Brownbridge (daughter of
Elisha and Rebecca Case) 1854-1939. Hopefully someone on the list
recognizes these people. I have information about their descendants that
I'd be happy to share, but nothing on their ancestors.
