About a year ago, we put out a want ad for Billy Bruce. This year, we found him, in London, England, but the year of his birth date is incorrect; it should be 1904 not 1903. Otherwise all the house cusps that Marc Jones mentions in his book The Sabian Symbols fits using his Placidus format.
His parents were William and Clara Bruce, also of London and was their eldest child, and only son, followed by his sisters Violet, Clara and Queenie. They lived in the Shoreditch South of London, i.e. the East-End.
Mr. Bruce has an ascendant of 13 Gemini with Pluto is his first house, though it was yet to be discovered at that time, suggesting that he had a great voice for the stage but I could find no mention of him there. He has Neptune in Cancer in the second house so his inborn talent was music. Saturn is right on the tenth house cusp in its essential house of Aquarius but too far away from its co-lord Uranus to make an aspect. Saturn does though make a sextile to Mercury at 16 Sagittarius suggesting that he may have turned his talents to acting and done better through his hard work and innate talent. The Moon is semisextile Pluto and perhaps he came of age through radio and teleplays. Hopefully though now with some location in our repertoire, our final search will go better.
