I found the following information in the Elk County, Pa records:
Born on July 15, 1902, E. J. (Male) Callen. Father, Thomas. Mother, Hilda Callen; birth of William Roscoe Callen, on Decemer 16, 1898 at Rainetown, (a ghost town since the mid 1900's) in Elk County, Pa. Father, William Thomas. Mother, Lucy Susan Riggs. Wife, Goldie Delphine Baker. Marriage May 11, 1920, in Maryland. Also, found online at familysearch.org the following: John Henry Callen, born 1842 married Adeline Mohney, born 1848 in Elk County, PA. I have no connection to the Callens other than the surname came up while I was compiling names of people who once resided in the Elk county area.
