lol I was hesitating to get the ancestry membership because it costs so much, but I decided to go with a free trial for now, since you gave me a solid lead.
With your jumping off point, I was able to actually track down the exact plot of land that was granted, and the record of it.
... not what I was going for exactly, but it's a nice milestone.
I'm still going to continue trying to bridge the connection between Allen and the other Allens.
Hopefully at some point I can afford to get a Y-DNA test for my living grandfather Allen while he's still around. I've been motivated to do his side of the genealogy because he really enjoys the time we spend together talking about it.
I've told him about Covington Allen before, and I'm hoping to give him another good story about things the next time I see him.
If you come across any other leads, please let me know, or throw them into a Research notes.
Otherwise, I'll try to work with what you've gotten so far.
