Until his Cherokee wife and four kids came along, Marc Quartermaine was the only long term Quartermaine child born entirely in America. His accent wasn't sounding like those of his parents, instead it sounded a bit Hoi Toider!
Life was shit for him before meeting long suffering, stubborn Dee, since his parents daringly fought against each other in the most maniacal way possible for a long time until they died.
The only word written by him on record is 'Oo kah huh sdee', which pretty much makes some sense, because the Cherokee language has such an eponymously unique word to describe the delight of a kitten or even the good side of it all.
The stubborn couple had four kids together until they separated. Whereas both died 4 years apart, three of their kids, except for the youngest named Thunder (it is possible that in the olden days, the youngest kid generally but didn't always survive), died in the worst conditions possible.
