Researcher Larry Lieneke does not claim that David Thompson Jones and Jane Porter are the parents of Thomas T Jones, but he does argue the pros and cons in his research. His GenForum posts are archived at https://www.genealogy.com/forum/users/9192909/.
Thomas T Jones did name a son "David", another son "Thomas Porter", and another son "William" (perhaps for alleged brother William Porter Jones).
This profile formerly gave Jane (also indexed as "Jean" in some marriage record databases) a first name of "Elizabeth". The source for this is unknown, but it may be based on an Ancestry.com hint that suggests this Jane Porter Jones may be the same as an Elizabeth Jones who is a widow of a Thompson Jones in a Civil War pension in Ohio. Given that our Jane's husband David Thompson Jones was at least ninety when the Civil War began, if he was even still alive, and that Jane is not seen in the census after 1840 (if that is Jane and not a later wife), any connection to Elizabeth Jones of the Civil War pension in Ohio is extremely unlikely.
At this time there is no known segment triangulation between descendants of David Thompson Jones and Jane Porter.
Descendants of Thomas T Jones through daughter Elizabeth Jones Thompson have "ThruLines" suggestions for Jones and Porter as parents of Thomas T. The purported other children of Jones and Porter are "Francies" and "William Porter" and a private match. However, the number of matches for the theorised connection are few (seven) and of small size (10 cM for the largest segment - a 25 cM match connects on a closer line).
