I am searching for information about my Great Grandfather and his family. I only know that he came to New York, from England, married Rachel Marcuse and then moved and settled in North San Juan, Nevada County, Caliornia. He was a "horse and buggy" doctor in the Grass Valley/Nevada City area, having been educated in Edinburgh. I am directly related to him by my Grandfather, Hubert Lucas Samuel. Any information would be appreciated.
