I was recently indexing a sheet from the Indiana 1900 U.S. Federal Census and encountered the following family:
John T. Killey b. July 1868 Isle of Man, immigrated to U.S. 1890
Eliza wife b. July 1874 England, immigrated to U.S. 1885
Catherine E. b. Jan 1899 Indiana
In the 1910 U.S. Census for Indiana, there are two additional children:
William K age 7 b. Indiana
Frances A age 4 b. Indiana
In the 1920 U.S. Census for Indian, one addition child is listed:
Jessie M age 7.
I have been unable to link John T to a family from the Isle of Man.
