Robert and George both gave the month of Robert's birth variously as October, November or December.[5]Jeaffreson & Pole (1864a, p. 7) states that although he celebrated his birthday on 16 November, the October date was determined by looking at an extract from the register. Most biographies, such as Rolt (1984, p. 10) and Davies (1975, p. 8), give this date of birth except Ross (2010, pp. 21, 288), who gives the November date because George Parker Bidder was invited by Robert to a birthday party on 16 November 1852, and Robert's birthday is noted in Bidder's diary in 1853, 1854 and 1875.
