 Susie Bootja Bootja was born circa 1935 near Kurtal , or Helena Spring , south @-@ west of Balgo , Western Australia ; the country is called Kaningarra in her own language , a name that appears as the title of one of her art works . The ambiguity around the year of birth is in part because Indigenous Australians operate using a different conception of time , often estimating dates through comparisons with the occurrence of other events . While sources vary as to Susie 's skin name ( some indicating Napangarti , others Napaltjarri ) , the similar birth dates , locations , and work history indicate that all are referring to the one individual .
