I have a PDF copy of Henry A Clark's 1929 death certificate, if you would like it.
Henry's daughter by his South African marriage was Elizabeth Jane, but she was mostly known as "Lillian".
Also, I have established that Henry -- or "Harry" as he was called -- arrived in Australia and is recorded thus in the Passenger Arrival listings:"Name: Clark, Hy, Age: 36 yrs., Month: Aug. Year: 1881. Ship: 'Australisian'. From port: British Port.
His daughter is listed thus:"Name: Clark, Lillian.Age: 11 yrs.Year: 1888.Ship: 'Iberia'.From port: British.
So it appears Lillian may have been sent out by herself, or with a chaparone...or Henry went back and collected her, but has not had his (second) entry details entered (or discovered).
Folklore: It is said that after his wife Elizabeth died, Henry put Lillian in a Catholic orphanage in South Africa.It is said that he then went off to East Africa (now Kenya?) to do dairyfarming...
