What you have kept and the sources you added look really good. I looked at the change log to see what had been there too. There were a few clues which I would have kept in a Research Notes section:
1. Military Service: War of the Rebellion (Civil War), Company K, 7th Kentucky Infantry/ Kentucky
2. Robert Paul Lewis and Jean Walker, Collected Family Records of the McSpaddens in America, May 27, 2000.
3. Beverly June Speak, Speak Family Records, (Oct 2002), "Electronic." http://worldconnect.rootsweb.com/cgi-bin/igm.cgi?op=GET&db=:2264359
4. Rick Cowart, Cowart (Rick) Family Records, (Jul2001), "Electronic." http://awt.ancestry.com/cgi-bin/igm.cgi?op=GET&db=rickc
While none of those are primary sources or reliable, they may contain gems which would help flesh out his profile. The names of other researchers, clues for records to look for, etc.
For instance, the Military Service line gave me enough information to find this:
"United States Headstone Applications for U.S. Military Veterans, 1925-1949," database with images, FamilySearch (https://familysearch.org/ark:/61903/3:1:33SQ-GP8X-4DQ?cc=1916249&wc=MDBV-5Z9%3A205942801%2C206048401 : 17 May 2016), 1925-1941 > Baker, Cain-Barnes, William H > image 1054 of 2726; citing NARA microfilm publication M1916 (Washington, D.C.: National Archives and Records Administration, n.d.).
The Speaks Family Records link required some drilling down to Nicholas' profile at http://wc.rootsweb.ancestry.com/cgi-bin/igm.cgi?op=GET&db=:2264359&id=I03183 but then I found a notation that her information came from the "Speak/e/s Family Bulletin, March 1994, p. 14." I clicked the link to Nicholas' alleged father and found another possible research avenue in a citation to the book "Early Settlers of Lee Co., VA", p. 713. -Also, on p. 950 ... etc."
DJ tells me that she had those sources also and will be adding them to the bio as time permits. The advantage of a collaborative tree is that, with the clues, others might add them for her while she is working on something else. Thanks, DJ, for letting me share our conversation.
