Hi Daulton. No worries, 99.7% of us on WikiTree are not professional genealogists.
I was just noting that if the 1850 Census data above is the person we are looking at, then the profile here has a date of birth that is 20 years out of sync (too early, more than could be accounted for by census taker error) and the birth location might be off. Given the period in history and possible geographic locations, I would question dates and locations on the profile until they are documented by primary source information. Your idea on the family relationship may be entirely right and the info on the profile wrong (no documentation for what it says).
On the linked profile, only son Joseph is showing descendants. And, his profile is entirely unsourced other than a census record.
My suggestion, though it will take a little time, is to approach your puzzle a little differently because the entire family is unsourced. I would go downstream to perhaps Martin Lee Black (since he supposedly lived until 1966), document him and his parents, then work backward. That way you will always be working back from documented people and locations. Doing it the other way you run the risk of looking for family relationships where none may exist. Working the question from a later generation and moving back could also point up if James Black b 1822 is perhaps a nephew of Robert Black b 1787 rather than a son. Working from Robert downstream you might not see that if it were the case.
If this is part of your family, consider adopting these orphaned profiles since you may be working on them anyway.
