Are you still researching this Taylor line? My son in law is the grandson of Frederick's elder sister Eva Muriel Taylor. Their father, as you say, was Edward James Taylor b 1884, an only child, and his father was Edward Taylor born 1862, whose birth certificate I'm awaiting. Edward and his wife Margaret Flannery married in Nottingham on 10 Oct 1880. I have their marriage cert. Edward names his father as Thomas Taylor, hawker, but I can't find him in a census, and I'm a bit suspicious as Edward's mother's maiden name was also Taylor, which is often a signal for illegitimacy. The family appears to have moved to Philadelphia in 1890 but were back in Nottingham before autumn 1904 when Edward James married.
