Speculation only here, but I wonder if Irene's father will turn out to be Joseph Edward Biney, who appears on the 1901 census as a Chartered Accountant aged 22, and then is on the shipping list going out to Gold Coast/Ghana in 1902, 1905 and 1919 (and dies in 1939, which is a whole other can of worms!). Obviously this is supposition, but I wanted to get this person marked out just in case!
