There;'s been some discussion lately about the 511 error code which it appears is produced if the first and middle names are unique, allowing profiles to be re-examined to see if the name is spelled correctly or not. A middle name which has been a bit of a stumbling block in my family is "Waton". It occurs as a middle name for Noah Waton Miller, my 2ggrandfather. You'd think it should be "Watson", but Noah's middle name is only spelled out on the back of a photo I have of him. which I've scanned in and upload (as well as the front) just now. If anyone can find an early document for Noah with a spelled out middle name or a reason he might have either Waton or Watson as a middle name, I'd appreciate it.
