Frank Dann B.1886 MO,AR

Can anyone help me find descendants?

My Great grandfather Frank Dann was born
10-10-1886.
He married Lula Pearl Stack b.8-4-1892.
They produced a daughter Dorothy Juanita Dann 5-2-17 in Giddion,MO.(my grandmother)(d.1990)
I think they later moved to Arkansas (Augusta area) where my grandmother met my grandfather.
