Thanks Doug.I did email some of the Canadian descendants as you suggested and one has now kindly provided me with a copy of the possibly well-circulated family photo from around 1906 featuring George Frederick OLDAKER and his third wife Emmeline Annis Paget SWEENEY plus others.
It is the identification of the 'others' that seems to be a bit hazy as there are discrepancies in identification depending on who is looking !
The one thing that they are agreed upon is that the seated woman with child on her knee is not a child of this marriage and there is speculation or indeed assertion that she is 'from an earlier marriage of George'.
Well, it cannot be either of his earlier wives as they were both long dead by 1906.
Going by the estimated age of the seated woman, I would think that it could be either of his daughters Edith (born 1862) or Louisa (born 1870) from his second marriage to Louisa LUDBROOK (d.1883). This would make them 44 and 36 respectively in 1906 and this I think matches reasonably well the apparent age of the seated woman in the photograph.Both were (or had been) married and at least Louisa had children (born 1896 and 1900 and possibly others) to tantalise us further.
That said, I have no photo to go on of either of the daughters of George from his second marriage.So it is all speculation - unless someone out there can confirm or deny ?
I would be interested to see any photo of George's children or indeed grandchildren (preferably identified !) if anyone from the now extended family can oblige.This could help to eliminate or confirm family likenesses.My email address is firstname.lastname@example.org .
My wife, a great-great-grand-daughter of George Frederick, did suggest the unhappy possibility that the seated woman could be a servant ...!But that is being pessimistic I think and so I just keep digging optimistically.
