According to the "George Shuman Family History" Cornelius was born Apr 2, 1877 in Santa Barbara, CA. I have not been able to verifiy this info as of yet. His wife was Edith Shuman and she was born in IL. The Shuman family migrated to CA in the late 1890's, so I'm not sure if the Lyman's migrated as well or if they families met once the Shumans arrived in CA.(Edith & Cornelius were married in 1900).
As for Lorenzo, the only other information I have on him is that his middle name is Snow. Leanne
