Hope you check this forum for follow-up. I don't recall if we have previously communicated, however, I lived in Napa for 30 years up until 5 years ago. We share mutual ancestors - Charles Anthony Piner and Sarah Annetta Hand. Their daughter, Sara Catherine Piner was my gr grandmother. Her husband was Rufus Kirk Robison. I have quite a bit of data on the Piners and Hands. Happy to share. Please email.
