Don't know if you've figured it out yet, but the letters were "Jno"... not 'D*ng' as indexed.... this was John/Jonathan Scarbrough & Lula Love Auston... they ended up in 1920 in Perrine, Dade Co., FL before moving up to Laurel Hill, Okaloosa Co., FL before 1930... where they remained... John died bef 1935 & Lula died in 1960...
