I've been watching this since you first brought the question up. I'm related to Travis through his parents John and Violetta Hood (through Travis's brother Nathaniel Hood). I've DNA kits that have matched others through the Hoods, but so far I haven't found any testers down through the Travis descendants. I'd love to find some!
I've been working off and on (work and life keep getting in the way) on the relatives on FamilySearch, trying to use only good sources. I've repaired, merged, and sourced a number of profiles over there. I finally started bringing some of it over on Edith Hood's WikiTree profile, and you may want to check it, especially the sources and notes within the sources. (I don't write well or fancy, mostly a data driven approach.)
Some work on FamilySearch that may help:
If you check the change history on Travis, you'll see that someone removed Sarah Wilson as his wife, for what seemed like a valid reason. Now someone is adding her back, but without any sourcing or evidence. I've started a discussion there about her, plus mentioned the problem of whether Travis is the father or grandfather. There isn't solid evidence on it, which is why most of us have been very reluctant to connect Violet and Travis and Edith etc.
A tip - when possible I check the original of each Census and look at who is living nearby, as it's often helpful, sometimes surprising. Especially in farm country, you often find close relatives living very nearby. That's how I noticed that Edith and Violet were next to each other, and Elizabeth and Edith were next to each other in another Census. That's not proof of a kinship, but certainly suggestive. It's also a great way to find someone who's name has been mangled by either the census taker or the transcriber.
