Children or offspring, or more broadly, anything that is produced or created as a result of something else.
From Latin 'progenies,' derived from 'pro-' (before, forth) and 'gignere' (to beget or produce). The word has been used in English since the Middle Ages to describe descendants and has expanded metaphorically to describe intellectual or creative descendants.
Interestingly, 'progeny' doesn't have to mean just biological children—authors speak of their books as their progeny, and companies call their products progeny, showing how humans extend family language to anything we create or are responsible for!
