Kathy, I agree that this profile is far from being certified as completely accurate. As we all know, genealogy is not instantly clear. It may take several more generations before this particular family can be proved with absolute accuracy. We often have to make nebulous links to family members, and then try to approach the family from a different angle to see if the data proves or disproves the family.
The family of Meriwether Lewis is entitled to this same courtesy.
Keep in mind that this particular family lived in the old Dakota Territory when it was opening as a frontier to Europeans. Tensions between Native Americans and Europeans were high, and there are numerous examples of blood shed, not only in wars, but in one on one confrontations of Native American families and European families. The Dakota Territory was on the other side of Illinois, and Illinois was not even a State. My ancestors, who were among the very first of the homesteaders after the Revolutionary War, settled in Southern Illinois right around 1799-1800. Meriwether Lewis lived even before this time.
The distrust among the races was a major source of anxiety for everyone at that time. Meriwether Lewis was caught between the cultures. He was relying on the friendship of the Native Americans to help him take their land away. His job was far from enviable.
If the Native Americans say that Meriwether Lewis was their ancestor, it is not something they would have advertised widely in the early 1800s. It would have been a source of shame, not pride. What motivation would there be in the 1800s for the son of Meriwether Lewis to claim him as his father, when his ancestry was Native American? He didn't make such a claim until later in life, when he and his family finally forsook their cultural heritage and sought baptism at an Episcopal church. It was a very sad time for them, not a time for inventing relationships to the man who led the expansion of the United States.
It just wreaks of bigotry to say that Joseph DeSmet Lewis could not be trustworthy due to the timing of his claim. If anything, the timing of his claim proves that he is, in fact, the son of Meriwether Lewis. He was finally broken in old age and only after a long life surrendered his native culture. I would think that of all people, you would understand that.
