Private User points out that the above list of children of Walter David Peter Doubell is not complete, taken from an early edition of Suid-Afrikaanse geslagregisters; there are at least three children not mentioned: Sarah Anne Miles nee Doubell, Eva Catharina Johanna Stoffelina McLeod nee Doubell, and Douw Doubell.
It seems to me that Walter David Peter Doubell, c4 born 1861 is likely to be another child of this 2nd marriage, given the exact same First and Middle Names, and the 1861 birthdate in the gap between the 1859 marriage and the c1863 birthdate of the present c4 first child.
It is not impossible, though, that he is a child of one of Walter David Peter (b2)'s brothers.
Any thoughts?
