My character sometimes talks about her people and that includes her great grandparent's generation that initially fled Earth and arrived at the new planet before she was born. "Ancestors" sounds more distant than "great grandparents", and "great grandparents" sounds like just her single family line of descent, but she is referring to a large group of many families. So which term do people think is more precise or fits better when she is talking about her people? Or is there a better term than either of those two choices? Thanks in advance.
