According to Bijsterveld and Toorians (2018), "it can be plausibly argued that those living there as well as the neighbouring population may well have kept the geographic reference to the Texuandri (or to the territory named after them) in use." In sources of the period 709–795, the "pagus Texandrie" appears to be concentrated around the basin of the river Dommel and its tributaries, between the towns of Alphen, Waalre and Overpelt. It was later extended from the 9th century onwards as the result of a growing network of local alliances.
