Good morning Kitty,
My father was born in Bluefield, WV and his LNAB was Snider. Dad's father was Garland Clinton Snider and I have records that go back to Sneider but I don't have any other sources besides from Ancestry (when I first started in 2013 and not the most reliable source, IMHO) and that seems to trickle down to me with the Snider name being consistent.
I can honestly say that by working with genealogy since 2013, and having many ancestors on my tree, NAMES are a big issue.
Names change in every tree, depending on the whims of the parents. My own FIL changed the surname of the kids by adding an S to the name. In really old times, Bloody Mary changed the Stewart name to Stuart because she had a feud with someone with the previous spelling so she assumed her right to change the spelling.. and the list of reasons go on and on. I had a fun time with the Lindsay and Lindsey names. 3 hours of work with that one.
So.. if you can find a DATED reason.. you have a ghost of a chance of knowing the LNAB spelling. But otherwise.. you have to do the best you can and list AKAs.
Good luck and happy hunting.
