Abraham did have a son named Stephen M. Burkdoll and also an older brother named Stephen. The genealogy that I have on all of the Burkdoll line is at this web site on Rootsweb/Ancestryhttp://worldconnect.rootsweb.com/cgi-bin/igm.cgi?db=jlnoell
The son Stephen is listed in the 1850 census for Howard Co, IN while living with his father and siblings. They had moved there from Swizterland Co. IN. He married Phobe Ann Richards:

The brother Stephen I have married to a Catherine. However I have not found where he migrated to from PA and was wondering if he was the Stephen Barkdoll found in the 1830 census for Dearborn County, IN. or the 1810 OH census. The last census I did find him in was the 1800 Addison Twp, Somerset Co, PA census as noted on the notes on my web page.
There is confusion on the spelling of the Burkdoll in various documents. I have seen it in the indexes as Barkdoll, Berkdoll, Barkdoll and various other variations.
