Looking for information on my grandfather Otis Allen Ping, Born February 5, 1872, Sperry, Iowa. Also any information on his sister, Cornelia, born 1878. These were the children of James Carother Ping, born November 27, 1874, Des Moines County, Iowa. James was Married to Clementine Scott. Would like more information about Clementine and her family. Any help will be appreciated and I may have a little information to share.
