'home-born' is a compound of English 'home' + past-participle adjective 'born'. 'Home' comes from Old English 'hām' meaning 'dwelling, village, estate'; 'born' is from the past participle of Old English 'beran' meaning 'to bear (give birth)'.

'home' developed from Old English 'hām' into Middle English 'home'; 'born' comes from Old English 'boren' (past participle of 'beran'). The compound 'home-born' (also attested as 'homeborne'/'home-born') appeared in Middle/early Modern English to denote someone born at home or native to a place.

Initially it meant literally 'born in the home' (a description of place of birth). Over time it also acquired the extended sense 'native-born' or 'originating locally', and occasionally a figurative sense of 'produced domestically'.
