Hi Shirley,
I wondered if you found any information? My grandmother, Eleanor Selby Gist, was the only daughter of Louis P. Selby, Jr. and Genevieve O'Neill. I'm currently researching the O'Neill part of the family, but it's very interesting that the original name was De Silva. That is something I didn't know. I do know the family had a very successful chocolate store in the Bay Area.
Thank you!
Deborah
