Your family line is impossible. Your great grandfather died in 1811. Which means your grandfather was born pre-1811. Let us say your grandfather was born in 1810. Even if you were 100 years old now, so born in 1898, your father would have to have
been 88 years old when you were born. Do you mean your great grandfather died in Colombo in 1911.
