I added source evidence to the profiles for Josiah & Henry Ligon Holt who is his currently attached father. I don’t see anything one way or another. Would you like a parent disconnect? If evidence is found, they can always be reconnected.
For that matter, I'm not confident the ancestry ascribed to Henry Ligon Holt is based on unambiguous sources. It looks to me like naming patterns, geography, and census records invite the conjecture that he is a Ligon descendant, but that's not what I would call proof positive, and he could easily have been named that simply out of admiration for someone in the Ligon family. Here as with the connection to Josiah, I would be most pleased were that proof to materialize, but I'm skeptical.
