Los Frazer parecen ser otra familia sin relacion con los Fraser.

As to Mrs Frazer's diary, the source for my quotation was Dr Bruce Taylor , who wrote to me on 3 June 2002, as follows:

"I am the great grandson of John Frazer, an Inverness schoolmaster. In 1879 he embarked at the Port of London to establish the first school at Port Darwin in the Falklands. His wife left a superb diary of the journey south and arrival in the Falklands which I am planning to publish. In 1900 he left Port Darwin with his wife and three adult children (including my paternal grandmother) to settle at San Julian.
The ship that took them there was the famous 'Rippling Wave', long a beached wreck near Punta Arenas. The family acquired Estancia La Colmena some miles from the town and developed a successful wool business, purchasing other estancias in due course. John's elder son, John Bruce Frazer, ran the business after John Sr's retirement to Arbroath in c.1910. John Bruce had nine children, two of whom were lost in the 'Avila Star', torpedoed by U201 in the Atlantic in about June 1942 with a number of members of British community in BA. Several remained in the Argentine, others settled in England and one in Australia. Most are now dead. A number of family members are buried at La Colmena itself. La Colmena was sold to an American company in 1978. Throughout its time in Patagonia the Frazers were closely connected to the Patterson family, also Kelper Scots.
Apart from the books you mention the following volume is of interest for the early settlements in Patagonia:
Robert & Katharine Barrett, A Yankee in Patagonia: Edward Chace, his thirty years there 1898-1928, intro. R. Kent. (Cambridge: W. Heffer & Sons Ltd., 1931)
I hope this of interest. I'd be most interested to know what your connections are with this fascinating aspect of Anglo-Argentine history.
Best wishes,
Dr Bruce Taylor
Los Angeles, California”
