Mrs. W. R .Freemantle, whose death was recorded in the last issue of this journal has been a resident of Burgersdorp for upward of 46 years, and was at the time of death 68 years of age.  Her husband died some 25 years back leaving to her care a family of three sons and two daughters, all of whom survive their mother.  They include William Freemantle of Indwe, John of this district, and James of Dordrecht, Mrs. Broster of Broughton and Miss Annie of this town.  The funeral took place last Wednesday and was well attended by both English and Dutch friends.  Rev. Ecclestone officiated.  The deceased and highly esteemed lady is laid in the same grave with her husband.
From another newspaper cutting:
I have to record the death of another of Burgersdorp's oldest and most respected residents in the person of Mrs. W. R. Freemantle.  This lady has for many months past been in weak health and as she in May last reached the ripe age of 68 years it was felt that her death was only a matter of time.  On Monday night at twelve o'clock she passed peacefully away.  Her children who were all residents of this and adjoining districts were present to bid the last farewell to a tender and devoted mother.  The deceased has resided here for some forty years and is widely known in the district.  To her various relatives and friends the community tenders respectful sympathy.  The funeral will take place at 4 o'clock this afternoon.
From a letter by Jill (Aletta) Thornton-Archer.  10.10.1971.
At one time Arthur (my brother) and Margaret Deane's father, Tommy Goulding were very interested and unearthed some facts including a report that my great, grandmother - whose surname they told me was Pitt, nee Roberts [Sarah Pitt, mother of Phillis] was buried at Clumber near Bathurst, they never found her grave tho' they made a special trip to search for it and I never found it either though I went through the cemeteries at Bathurst, Clumber,  ... ?, and Trappes Valley, etc.  It is possible that there was no headstone.
