I am the eldest granddaughter of Atoa Polito & Faagutu Tugaga. Just want to let you guys know that the Samoan translation/interpretation of the name Blacklock is Palatilota. I worked in the Supreme Court & the Legislative Assembly in Samoa mid-1960s - 1980s, and that was the translation used in Samoa, even now. There is also another surname Blakelock in Samoa, the same translation "Palatilota" is also used. Hope that helps.
