The Sambalic languages are most closely related to Kapampangan and to an archaic form of Tagalog still spoken in Tanay in the province of Rizal. This has been interpreted to mean that Sambal-speakers had once inhabited that area, later being displaced by migrating Tagalog-speakers, pushing the original inhabitants northward to what is now the province of Zambales,[3] in turn, displacing the Aetas. There is also a possible relationship between these Sambalic language speakers and the population of the island provinces of Marinduque and Romblon based on commonalities in some traditions and practices.
