Hi!
My mother is doing genealogy work. She's focused on who we think is our immigrant ancestor, and is using Civil War military documents to trace the movements of the ancestor in question. She's currently going through Union Mustard Rolls, and keeps coming across this symbol: a horizontal line with an x through it, with 6 dots filling the spaces in between each line. I tried Google image searching, but all that came up was Celtic protection runes, which were close in design, but not the same thing. If anyone knows what I mean or can answer as to what it might be, I'd love to hear from you!
