I am very, very new to all of this. My great-grandfather was John Seahorn. He and my g-grandmother Martha died in the flu pandemic of 1917-1918 (probably in Texas). They had 3 children. Two were deaf. My grandmother, Lelia Mae, was sent at the age of 8 to an orphanage in Oklahoma. I cannot find anything on John Seahorn. I can use all the help I can get. Thanks.
