George Louis Alke Duff Quartermaine was born in 1854. Being the third and youngest of the first Quartermaine children and second to survive, he collaborated with his big brother in acquiring the Burns brewery in 1876. They renamed it Duff beer and the name stuck ever since!
Before that, their older brother Pongo lived a short life, lasting for about seven months before dying of measles.
He was not as pervy as his father, instead he was simply more cautious. He lived for about 84 years and was married to family friend Ida Zemlock for about fifty six years, two thirds of his life. Ida was also his ally cum soulmate, as both were children of the filthy rich entrepreneurs, even though her family was Austrian Jewish in origin.
An avid treasure hunter going solo - even as Edgar became too monstrous to handle, he pretty much escaped the dad's wrath along with big brother Howard.
Ida and George fostered Melissa, Yetta (Howard K Duff's daughters) and Kerchak Duff (Howard K Duff's son) as if they were their children, although they're actually their nieces and nephew. Yetta was the eldest, born in 1876, with Kerchak and Melissa being fraternal twins, born in 1884.
After they all left the house to demon hunt, Ida bore George a foul mouthed son named Ezekiel in 1901, shortly after Edgar died. Because they're latecomers in the Quartermaine parenting game, Ezekiel was their only child, and that's it!
George died in 1938, while Ida survived into WW2, when she died in Hawaii in 1942.
