。
She talked about her family.
Literal
She [topic-は] her own family [about-について] talk [object-を] did.
話をする ('to have a talk, to give an account') is the verb-form alternative to plain 話す ('to talk'). Splitting into 話 + を + する slightly emphasizes the talk as an event or activity rather than a continuous action — 'she had a conversation about her family,' suggesting a defined episode rather than ongoing chatter. ~について is the standard 'about / concerning' compound particle.
