Yes, there were survivors...I am living proof of that. There were five killed in the attacks, but only one Smith, Jonathan's daughter, Mary, who was three years old and lingered six days before dying. Jonathan was shot through both legs and his hand. His wife, Mary Ann, was shot through the lungs, but somehow survived. She was also wounded in the hand, which was crippled for the rest of her life. My ggrandfather was hit in the hand, as was John Adam Smith, his father. A lot of hand injuries!
The Smith's all settled in California...Sonoma, Georgetown, Fowler, Biggs, Paicines, and Monterey County.
All the Smith family came west on that train except James Henson Smith, who lived out his life in Iowa, never coming west, and Isaac Smith, who lived in Ohio, and later came to California after serving in the Civil War. Isaac ended up in Fowler, Ca. The only Smith to live in Washington or Oregon was John Christian Smith, who moved around the country, finally settling in Egypt, Washington. He moved back to California shortly before his death in 1912.
John Adam Smith was the patriarch of the family. His children were, Isaac, Elizabeth, Rebecca, James, Lewis, Mary, Jonathan, John, Buchanan (my ggrandfather) Lavina, and Caroline.
If anything sounds familiar, let me know.
