I found a slightly different newspaper mention which is very much the same as the one Andy_T posted, but mentions a brother of George's. I'm just tossing it out there in case it is of some interest to the OP.
Colonial Times 01 Oct 1850 Pg 2
DIED
At Manila, in April last, in the 25th year of his
age, Mr. George Brown, youngest brother of
Charles William Brown, Compositor,
Colonial
Times Office, Hobart Town, for many years in
the employ of Mr Richard Dawson, Ironfounder,
George-street, Sydney.
At the same place, in May, in the 23rd year of her
age, Mrs. Brown, wife of the above, and
eldest daughter of the late Mr. Edward Wood-
ward, of Phillip-street, Sydney.
Majm mentioned that Richard Dawson, was a significant person, so for anyone interested:
