- See the Valerii disambiguation for additional entries related to "Valerii".
Katherine Valerii was claimed by Sharon Valerii as her mother on the mining colony of Troy, apparently killed during a disaster on the colony (TRS: "Flesh and Bone"). She was married to Abraham Valerii (TRS: "Kobol's Last Gleaming, Part II"). Sharon was in reality a copy of Number Eight with no biological parents, so the Valeriis were either nonexistent or a couple unrelated to her.
- According to series co-creator Ron D. Moore in a 10/24/05 interview on "The Chase Show" on the SF webcast news site TheFandom.com, there was never a human named Sharon Valerii. This information eliminates the possibility that Katherine was Sharon's actual mother, although it does not eliminate the possibility of her existence on Troy.
- There are multiple spellings of Katherine. This one was taken from the DVD subtitles.
