Yes! Theophilus died in the Civil War, as did another brother. I don't have his children in my computer file yet, but can look them up, if you would like them. This gives you the line back to Robert Allen and Ireland.
There's a Civil War widow's file that I don't have on him, and can be ordered from the NARA.
Here's what I have on your Theophilus:
