It's spelled the right way so I knew it was from the same family. After spending some time on both Google and LDS Familysearch, I was able to make the connection. The street is named for Dr. Benjamin Shurtleff, MD, who lived in Shasta and later moved to Napa in the 1800s. He originated from Massachusetts and sailed to San Francisco during the gold rush. He settled in Shasta and had a storied political career in addition to his medical career.
From what I could find, Benjamin is 4th cousins to Luman Andros Shurtleff and they lived about the same time. They both come from the William Shurtleff line - William Shurtleff was one of the first Shurtleffs from England during the colonial period, back in the 1600s. Luman Andros was descended through William Shurtleff's first son, William, while Benjamin was descended through William Shurtleff's third son, Richard or Abiel.
