Hi Cindy,
We never delete profiles on WT; if you do decide to disconnect Phillip from these parents you should leave a note with your sources both on his profile and on his parents profiles so future researchers will know what you based your decision on. Geni and RootsWeb (that link appears to be broken) are not acceptable sources for pre-1700 profiles, and FAG is very iffy (depending on whether there is a photo of the actual gravesite). In this case, I am not certain how it could be used to prove or disprove parentage.
