The unconfirmed information that I have is that he was born in New York around 1810. He was married on 31 December 1837 to Mahala Davis, who was born somewhere in Kentucky around 1817.
Ralph and Mahala had three children: Ralph D. Warren, born 17 November 1839 in or around Warrick County, Indiana, Mark Warren, born around 1840, and Jane Warren, born around 1845.
I assume then, that Ralph migrated from New York to the Kentucky/southern Indiana area sometime in the late 1830's. I seem to keep running into dead ends in my search for further information. Anyone who might have any clues, please email me at mtevault@verizon.net
