That is cool!
If you are a history buff like me...
I'm pretty crap at European history, and I would've never spotted the problem you detailed.
I want to clarify one thing I said earlier, the part where I said we don't know much beyond the couple of details I listed about the first one of our name here. What I should have said is that while we know quite a bit about his life in Louisiana, we knew very little about his life
before coming here, i.e., where in England was he from, why did he leave, what was his background and his family's background, etc. His life in southwest Louisiana is actually well-documented for its time. He kept a detailed diary, and that diary is today held by one of the historical societies in the area and is considered one of the main primary documents for the history of Lake Charles, LA. Most interesting is that he became the first school teacher in the parish (county, for all you non-Louisianans), which is kinda cool. His son married the daughter of another southwest Louisiana man (who would also be my ancestor, though not of the same name) who fought at the Alamo in 1836. Which has always been bizarre to me, because I don't know the story there at all.....like, why did this guy pick up and go to San Antonio and battle for Texas independence? We don't know. But his name is on the wall at the Alamo, and I've always scratched my head in bewilderment as to what that Louisiana-boy was up to.
Maybe that's why I've lived in Texas so much.....being drawn to TX is just in my blood

To SFBadger's point about stuff we're not proud of.... I mentioned we never knew much about the school-teacher's life prior to coming here, and there were always some hints that perhaps he fell out with his family and got cut off from them. Perhaps he decided to go elsewhere and make a new life, who knows. There were also more than hints that some other stuff to not be proud of lurked in his past. After the research my cousins did on him, the details are a little filled-in but still sketchy, but also the lost family members in California we've found through the miracle of Facebook had more verbal history to offer. It's still a lot of speculation on my part, so I hesitate to even put it out there, but filling in some gaps with my own best guesses, my theory is that he worked for his dad in something to do with the trans-Atlantic slave trade. I believe his father and perhaps he himself transported and sold slaves, and I hope I'm not incorrectly impugning their activities. Some kind of family falling out happened, and ties were cut and he settled in Louisiana. The "California cousins," who are black, believe he either married or attempted to marry a black woman, and that solves the mystery I always had of why there are black and white families with this odd English name, are we actually related, and if so, how far back do you have to go to find where that happened? Although a couple I talked to believe that it was darker case of an owner forcing himself on a slave. Yet others in both CA and LA think there was no blood relation and that slaves who were later freed just took the name of their owners. So getting back to "Theory A," that relationship ended, for whatever reason, after which he married a white Louisiana woman, and that's where we come from. There are a couple of reasons there he and his dad might have fallen out, if indeed they fell out.
If I'm right about any of that, then like SF said, it's icky.....but.....there's also not anything to do about it. Whatever happened, happened, and as SF says, here we all are.
