Roma Haynes Walker did extensive research on this family. What I have is about 433 pages in a Word doc. As you can see Thomas is #348. I don't know if she ever posted this information in the family tree section. If you search on the Riffle names above maybe you will find more info. I don't know that I can attach a file this large. I could try to email it to you in a zip file, but I'm not sure that will work either. I also see that she Roma's listed 6 of the 9 children. I hope this helps in your research.
