I do believe you are correct. I stopped working on this line a few years ago but just began again and actually found this information by census records before I found you posting. Henry's middle name was Welch. I do keep finding Nicholas as Nichols though. Even in the 1860 Macon County, MO Census which lists him as a female living with his mother Brookie.
